FOREWORD
Marines must have the versatility, flexibility, and skills to deal with
any situation at any level of intensity across the entire range of
military operations. Whenever the situation warrants the application
of deadly force, a Marine must be able to deliver well-aimed shots to
eliminate the threat. A Marine who is proficient in pistol marksmanship
handles this challenge without escalating the level of violence or
causing unnecessary collateral damage. It is not enough to simply provide
Marines with the best available firearms; we must also ensure that their
training prepares them to deliver accurate fire against the enemy under
the most adverse conditions without hesitancy, fear, or uncertainty
of action. A well-trained Marine is confident that he can protect
himself, accomplish the mission, and protect his fellow Marines. To be
combat ready, a Marine must be skilled in the tactics, techniques, and
procedures of pistol marksmanship and diligent in the proper care and
maintenance of the M9, 9-mm service pistol.
Marine Corps Reference Publication (MCRP) 3-01B, _Pistol Marksmanship_,
is the Marine Corps’ source document for pistol marksmanship and provides
the doctrinal basis for Marine Corps pistol marksmanship training. This
publication provides all Marines armed with a pistol with the tactics,
techniques, and procedures for range and field firing the M9, 9-mm
service pistol.
MCRP 3-01B supersedes the discussion of pistol marksmanship in Fleet
Marine Force Manual (FMFM) 0-8, _Basic Marksmanship_.

CHAPTER 1
THE M9 SERVICE PISTOL
The Marine Corps’ uses the M9 service pistol as a defensive weapon. It is
a semiautomatic, magazine-fed, recoil-operated, double-action pistol. The
M9 service pistol’s magazine holds 15 rounds and is chambered with a 9-mm
ball (NATO M882 round). The M9 service pistol has a maximum effective
range of 50 meters (54.7 yards).
_Note_: The procedures in this chapter are written for
right-handed Marines; left-handed Marines reverse instructions
as necessary.
Functional Capabilities
When the M9 service pistol’s safety lever is moved to the firing
position, it can be fired in either a single-action or double-action
mode. It is designed to fire one round each time the trigger is pulled.
When the last round is fired, the slide automatically locks to the rear.
Single-Action Mode
The single-action mode allows the pistol to be fired when the hammer is
cocked; single action requires the hammer to be cocked to the rear before
the trigger is pulled. The hammer can be manually cocked or mechanically
cocked. The hammer is mechanically cocked after the first shot is fired.
See figure 1-1.
[Illustration: Figure 1-1. Single-Action Mode.]
Double-Action Mode
The double-action mode causes the hammer to move to the rear as the
trigger is being pulled. See figure 1-2.
[Illustration: Figure 1-2. Double-Action Mode.]
Nomenclature
See figure 1-3 on page 1-2.
Major Components
The M9’s major components consist of the slide assembly, barrel assembly,
and receiver. See figure 1-4 on page 1-3.
Slide Assembly
The slide assembly houses the firing pin, firing pin block, striker,
extractor, and loaded chamber indicator, and it cocks the hammer during
recoil.
_Extractor_
The extractor pulls the brass from the chamber after the round is fired.
[Illustration: Figure 1-3. M9 Service Pistol.]
[Illustration: Figure 1-4. Major Components.]
_Loaded Chamber Indicator_
When a round is in the chamber, the upper surface of the loaded chamber
indicator protrudes from the right side of the slide. This protrusion can
be felt with the finger, verifying that there is a round in the chamber.
_Barrel Assembly_
The barrel assembly houses the round for firing, directs the projectile,
and locks the barrel in position during firing.
_Receiver_
The receiver supports the major components, controls the functioning of
the pistol, and holds the magazine in place. The front and back straps
of the grip are grooved vertically to ensure that the hand does not slip
while firing. The receiver consists of the disassembly button, slide
stop, and magazine catch assembly.
_Disassembly Button_
The disassembly button permits quick disassembly of the pistol.
_Slide Stop_
The slide stop holds the slide to the rear after the last round is fired.
It can also be manually operated to lock the slide to the rear or release
the slide.
_Magazine Catch Assembly (Magazine Release Button)_
The magazine catch assembly secures the magazine in place when loading,
and it releases the magazine from the pistol when unloading. The magazine
catch assembly is designed for both right- and left-handed Marines.
_Note_: Reversal of the magazine catch assembly for left-handed
Marines can be performed by a qualified armorer.
Safety Features
The safety features of the M9 service pistol include the decocking/safety
lever, firing pin block, and half-cock notch.
Decocking/Safety Lever
The decocking/safety lever, commonly referred to as the safety, permits
safe operation of the pistol by both right- and left-handed Marines. As
the safety is moved to the safe (down) position, the firing pin striker
moves out of alignment with the firing pin. This movement prevents the
pistol from firing as the hammer moves forward.
_Note_: In the fire (up) position, a red dot is visible,
indicating that the pistol is ready to fire.
Firing Pin Block
The firing pin block rests in the firing pin notch and prevents movement
of the firing pin until the trigger is pulled. As the trigger is pulled,
the firing pin block moves up and out of the firing pin notch. This
movement allows a round to be fired when the hammer strikes the firing
pin.
Half-Cock Notch
The half-cock notch stops the forward movement of the hammer during a
mechanical failure.
Cycle of Operation
There are eight steps in the cycle of operation for the M9 service pistol.
Firing
Once the safety is off and the trigger is pulled to the rear, the hammer
falls on the firing pin, which strikes the primer and ignites the round.
See figure 1-5.
[Illustration: Figure 1-5. Firing.]
Unlocking
As the slide assembly moves to the rear, the locking block rotates out of
the notches in the slide. See figure 1-6.
[Illustration: Figure 1-6. Unlocking.]
Extracting
As the slide moves rearward, the extractor withdraws the cartridge case
out of the chamber. See figure 1-7.
[Illustration: Figure 1-7. Extracting.]
Ejecting
As the face of the slide passes over the ejector, the case strikes the
ejector and it is knocked upward and outward through the ejection port.
See figure 1-8.
[Illustration: Figure 1-8. Ejecting.]
Cocking
As the slide moves rearward, the hammer is pushed back, allowing the sear
to engage the hammer hooks, cock the hammer to the rear, and place the
pistol in the single-action mode. See figure 1-9.
[Illustration: Figure 1-9. Cocking.]
Feeding
The slide starts forward, pushed by the recoil spring. The face of the
slide makes contact with the cartridge at the top of the magazine,
stripping it from the magazine and pushing it toward the chamber. See
figure 1-10.
[Illustration: Figure 1-10. Feeding.]
Chambering
As the slide continues forward, it pushes the cartridge into the chamber.
See figure 1-11.
[Illustration: Figure 1-11. Chambering.]
Locking
As the slide assembly continues to move forward, the locking block lugs
move into the locking block recesses on the right and left sides of the
slide. See figure 1-12 on page 1-6.
[Illustration: Figure 1-12. Locking.]
Ammunition
The only ammunition authorized for the M9 service pistol is the NATO M882
9-mm ball. Dummy ammunition can be used during training (a dummy round
has a hole drilled in its side and contains no primer). See figure 1-13.
[Illustration: Figure 1-13. M9 Service Pistol Ammunition.]
Do not open ammunition containers until the ammunition is to be used.
Ammunition must be maintained in a high state of readiness. To care for
ammunition—
Keep ammunition dry and clean. If ammunition gets wet or dirty,
wipe it off with a clean dry cloth.
Wipe off light corrosion as soon as it is discovered. Never
use ammunition that is heavily corroded, dented, or has the
projectile pushed in.
Do not expose ammunition to direct sunlight for long periods of
time.
Do not oil or grease ammunition. Dust or other abrasives can
collect on greasy ammunition and may cause damage to the
operating parts of the pistol. Oiled cartridges also produce
excessive chamber pressure.
Wearing of the M9 Service Pistol’s Gear
The proper placement of pistol gear helps ensure safety and aids the
Marine in effectively handling and employing the pistol.
M12 Holster
The M12 holster consists of the holster, removable holster flap, and
metal retaining clip. To check for proper placement of the holster, allow
the right arm to hang freely. The holster should be slightly in front of
the arm to permit easy access to the pistol upon presentation from the
holster. See figure 1-14.
_Note_: In most cases, the holster is issued with the holster
flap installed for a right-handed Marine. To convert the
holster for a left-handed Marine, remove the metal retaining
clip and install the clip on the opposite side of the holster.
[Illustration: Figure 1-14. The M12 Holster and Ammunition Pocket.]
M1 Ammunition Pocket
The ammunition pocket attaches to the cartridge belt on the side opposite
the holster in a position that best permits ready access for reloads.
The magazine is stored in the ammunition pocket with the rounds down and
pointed inboard.
M7 Shoulder Holster
The M7 shoulder holster consists of a holster with a thumb snap closure,
shoulder strap, chest strap, and a belt retaining loop. The holster
is positioned on the left side of the chest to provide easy and quick
access with the right hand. See figure 1-15. The M7 holster comes fully
assembled and has adjustable straps to accommodate each Marine’s body
size. The holster is available for right-handed Marines only, therefore,
a left-handed Marine has to withdraw the pistol from the holster with the
right hand and then transfer the pistol to the left hand before firing.
(See chap. 8 for transferring the pistol from one hand to the other.)
When the shoulder holster is worn properly—
The shoulder strap lays flat across the left shoulder with the
shoulder pad directly on top of the shoulder.
The chest strap attaches to the D-ring at the top of the
holster and runs diagonally across the chest, underneath the
right arm, and around the back where it attaches to the end of
the shoulder strap.
The belt retaining loop is at the bottom of the holster and
attaches to the belt to stabilize the holster’s position.
The ammunition pocket attaches to the chest strap directly
underneath the right arm.
[Illustration: Figure 1-15. M7 Shoulder Holster.]
Assault Holster
Some Marines (i.e., Marine security force, direct action platoon, and
military police) are required to carry the assault holster. This holster
has a retention strap that fastens over the top of the holster to retain
the pistol. This type of holster generally has a thumb break on the
retention strap that is disengaged to access the pistol. See figure 1-16.
[Illustration: Figure 1-16. Assault Holster.]
Concealed Pistol Holster
Some Marines are required to carry a concealed pistol as part of their
official duties. The primary consideration for placement of a concealed
pistol holster is to ensure the pistol cannot be seen; therefore, the
Marine must consider the type of clothing to be worn. A secondary
consideration is to place the holster so the pistol can be presented
easily. Typically, the best position for a concealed holster is just
behind the strong side hip. This position best conceals the pistol while
allowing it to be presented quickly. Another placement choice is in a
shoulder holster, placing the pistol just under the weak side arm. See
figures 1-17 through 1-20 on pages 1-8 and 1-9.

[Illustration: Figure 1-19. Wearing of the Concealed Pistol
Holster—Jacket.]
[Illustration: Figure 1-20. Wearing of the Concealed Pistol
Holster—Civilian Attire.]
Lanyard
The lanyard aids in pistol retention. It is issued in three sizes and is
adjustable. The lanyard consists of a fabric cord, two cylindrical slip
rings, and a metal clip that attaches the lanyard to the pistol’s lanyard
loop. See figure 1-21.
To don the lanyard—
Adjust the slip rings so they are positioned flush with the
lanyard’s base (clip end).
Place the right arm through the loop and place the loop over
the head, resting on the left shoulder.
Attach metal clip to the pistol’s lanyard loop.
Place the pistol in the holster.
Use the left hand to hold the bottom slip ring against the base
of the lanyard. Use the right hand to slide the top slip ring
upward to position the loop of the lanyard under the arm. The
lanyard should fit snugly against the body, but not restrict
the Marine’s movements.
Tuck any excess cord behind the holster.
Ensure that the lanyard is adjusted properly by removing the
pistol from the holster and fully extending the right arm. The
lanyard should be taut. Adjust as necessary.
_Note_: Re-adjust the lanyard if any equipment
changes are made (e.g., flak jacket).
[Illustration: Figure 1-21. M9 Service Pistol (With Lanyard).]
Firing the M9 Service Pistol While Wearing Gloves
Not all combat engagements occur during ideal weather conditions.
During cold weather, the Marine may find it necessary to wear gloves
to protect the fingers from frostbite and help prevent stiffening of
the hands. Gloves may also be worn in mission-oriented protective
posture conditions. Gloves provide protection to the hands, however,
they also may interfere with the Marine’s ability to engage targets
effectively. The added bulk of the gloves may affect the Marine’s ability
to manipulate the safety, magazine release button, magazine, hammer,
and slide stop/release. For example, the Marine may need to exert more
pressure to engage the magazine release or slide release buttons to
compensate for the thickness of the gloves.
The principles of target engagement (see chap. 7) do not change while
wearing gloves, however, the specific ability to manipulate and control
the trigger is greatly affected by the thickness of the gloves around the
fingers. Wearing gloves reduces the Marine’s ability to feel, which makes
it difficult to apply trigger control when firing. The Marine may find
that more pressure than normal must be applied with the trigger finger
just to establish initial contact with the trigger. Once the Marine
can “feel” the trigger through the gloves, then the pressure required
to fire a shot can be applied. This action may increase the chances of
firing the pistol prematurely due to excessive pressure on the trigger.
Dry firing while wearing gloves allows the Marine to learn how to apply
trigger control consistently and determines how much pressure is needed
to effectively fire a shot.
While wearing gloves, the Marine may find it difficult to fire the
pistol in the double-action mode due to the position of the trigger and
the limited amount of space between the trigger and the trigger guard.
Therefore, if the situation permits, the Marine may wish to thumbcock the
pistol to fire in single-action mode. In single-action mode, there is
more space between the trigger guard and the trigger, making it easier
to position the finger on the trigger. However, the Marine’s ability to
thumbcock the pistol may also be hindered by the gloves’ bulk. Therefore,
to thumbcock the pistol while wearing gloves, the Marine may perform one
of the following methods:
For method one, loop a section of 550 cord (approximately 2
inches) through the loop located on the top rear portion of
the hammer. The length of the cord should not interfere with
the pistol’s cycle of operation or with the Marine’s ability
to establish sight alignment. Once the cord is attached to the
hammer, take the pistol off safe and pull downward on the cord
to cock the hammer. See figure 1-22.
For method two, take the pistol off safe, rotate the pistol
inboard, and place the top of the hammer against a secure
surface (e.g., cartridge belt, table top, heel of boot). Apply
pressure on the pistol to keep the hammer in place and push
downward on the pistol in one continuous motion to cock the
hammer. See figure 1-23.
[Illustration: Figure 1-22. Cocking the Pistol with 550 Cord.]
[Illustration: Figure 1-23. Cocking the Pistol on a Secure Surface.]
Preventive Maintenance
If the M9 service pistol is to be effective, it must be maintained in
a state of operational readiness at all times; therefore, maintenance
of the M9 service pistol is a continuous effort. A clean, properly
lubricated, well-maintained pistol will fire when needed.
Pistol Disassembly
Before disassembling the M9 service pistol, ensure that the pistol is in
Condition 4. The pistol is in Condition 4 when the magazine is removed,
the chamber is empty, the slide is forward, and the safety is on. To
disassemble the pistol, perform the following steps in sequence:
Hold the pistol in the right hand with the muzzle slightly
elevated. Reach over the slide with the left hand and place the
left index finger on the disassembly button and the left thumb
on the disassembly lever. Press the disassembly button and
hold it in place while rotating the disassembly lever downward
until it stops.
_Note_: A left-handed Marine places the right thumb
on the disassembly button and the right index finger
on the disassembly lever.
Pull the slide and barrel assembly forward and remove it while
wrapping the fingers around the slide to hold the recoil spring
and recoil spring guide in place.
Turn the slide assembly over in the left hand until the recoil
spring and recoil spring guide face up. Place the right thumb
on the end of the recoil spring guide next to the locking block
and compress the recoil spring and spring guide while lifting
and removing them from the slide and barrel assembly. See
figure 1-24. Allow the recoil spring to decompress slowly.
Separate the recoil spring from the recoil spring guide.
Push in on the locking block plunger with the right index
finger while pushing the barrel forward slightly. Lift and
remove the locking block and barrel assembly from the slide.
A Marine is not authorized to disassemble the pistol any further than the
preceding steps. Any further disassembly must be performed by ordnance
personnel. See figure 1-25.
[Illustration: Figure 1-24. Removing the Recoil Spring and Recoil Spring
Guide.]
[Illustration: Figure 1-25. Disassembled M9 Service Pistol.]
Disassembly of the Magazine
To disassemble the magazine, perform the following steps:
Grip the magazine firmly in the left hand with the floorplate
up and the thumb resting against the flat end of the floorplate.
Release the floorplate by pushing down (with a blunt object;
e.g., an ink pen) on the floorplate retainer stud in the center
of the floorplate. At the same time, slide the floorplate a
short distance forward with the thumb.
Maintain the magazine spring pressure with the thumb and remove
the floorplate from the magazine.
Remove the floorplate retainer and magazine spring and follower
from the magazine tube.
See figure 1-26.
[Illustration: Figure 1-26. Disassembled Magazine.]
Inspection of the Pistol
Once the pistol has been disassembled, it must be thoroughly inspected to
ensure it is in a serviceable condition. Pistol inspection is continuous
during the pistol’s cleaning and re-assembly:
_Slide Assembly_
Check for free movement of the safety. Ensure the rear sight is
secure.
_Barrel Assembly_
Inspect the bore and chamber for pitting or obstructions.
Check the locking block plunger for free movement of the
locking block.
Inspect the locking lugs for cracks and burrs.
_Recoil Spring and Recoil Spring Guide_
Check the recoil spring for damage.
Check that it is not bent.
Check the recoil spring guide for straightness and smoothness.
Check to be sure it is free of cracks and burrs.
_Receiver Assembly_
Check for bends, chips, and cracks.
Check for free movement of the slide stop and magazine catch
assembly.
Check the guide rails for excessive wear, burrs, cracks, or
chips.
_Magazine Assembly_
Check the spring and follower for damage.
Ensure the lips of the magazine are not excessively bent and
are free of cracks and burrs. The magazine tube should not be
bent or dirty.
Cleaning and Lubricating the Pistol
Only authorized cleaning materials should be used to clean and lubricate
the pistol. If these items are not issued with the pistol, they may be
obtained from the armory. The following procedures are used to clean and
lubricate the pistol—
_Slide Assembly_
Clean the slide assembly with a cloth. A general purpose brush
and cleaning lubricant protectant (CLP) can also assist in the
removal of excess dirt and carbon buildup.
Ensure the safety, bolt face, slide guides, and extractor are
free of dirt and residue.
Wipe dry with a cloth and apply a light coat of CLP.
_Barrel Assembly_
Insert a bore brush with CLP into the chamber end of the
barrel, ensuring that it completely clears the muzzle before it
is pulled back through the bore.
=Caution=
Insert the bore brush through the chamber to prevent
damage to the crown of the barrel.
Repeat several times to loosen carbon deposits.
Dry the barrel by pushing a swab through the bore.
Repeat until a clean swab can be observed.
Clean the locking block with a general purpose brush.
Use the barrel brush to apply a light coat of CLP to the bore
and chamber area and lubricate the exterior surfaces of the
barrel and locking block.

Pistol Re-assembly
After the M9 service pistol has been cleaned and lubricated, it must be
properly re-assembled to ensure its serviceability. To re-assemble the M9
service pistol—
Use the left hand to grasp the slide with the bottom facing up
and the muzzle pointing toward the body. Use the right hand to
grasp the barrel assembly with the locking block facing up. Use
the index finger to push in the locking block plunger while
placing the thumb on the base of the locking block.
Insert the muzzle of the barrel assembly into the forward
open end of the slide. At the same time, lower the rear of
the barrel assembly by slightly moving the barrel downward.
The locking block should fall into the notches of the slide
assembly.
Slip the recoil spring guide into the recoil spring.
Insert the end of the recoil spring and recoil spring guide
into the slide recoil spring housing. At the same time,
compress the recoil spring and lower the spring guide until it
is fully seated onto the locking block cutaway.
Use the left hand to grasp the slide and barrel assembly,
sights up, and wrap the fingers around the slide assembly to
hold the recoil spring and guide in place. Align the slide
assembly guide rails onto the receiver assembly guide rails.
Push the slide rearward while pushing up on the slide stop
with the thumb. Lock the slide to the rear while maintaining
upward pressure on the slide stop. Rotate the disassembly
lever upward. Listen for a click, an audible click indicates a
positive lock.
Pistol Magazine Re-assembly
To re-assemble the magazine—
Grip the magazine firmly in the left hand with the floorplate
end up and the counting holes facing the Marine. Insert the
follower into the magazine so the flat end of the follower is
against the flat end of the magazine.
Ensure the floorplate retainer is attached to the first curve
of the bottom coil.
Hold the spring upright with the right hand and insert the
spring into the magazine tube so that the flat end of the
floorplate retainer is against the flat end of the magazine.
Push the magazine spring and floorplate retainer down with the
right hand and hold it in place with the thumb of the left
hand. Use the right hand to slide the floorplate over the side
walls of the magazine until fully seated, which is indicated by
an audible click.
Safety/Function Check
A safety/function check is performed after reassembling the M9 service
pistol. Perform the following steps to ensure the pistol is operational:
Ensure there is no ammunition in the chamber of the pistol.
Ensure that the safety is in the safe position, then depress
the slide stop, allowing the slide to return fully forward.
At the same time, the hammer should fall to the full forward
position.
Pull and release the trigger. The firing pin block should move
up and down but the hammer should not move.
Place the safety in the fire position.
Pull the trigger to check the double action. The hammer should
cock and fall.
Pull the trigger again and hold it to the rear. Use the fingers
and thumb of the left hand to grasp the serrated sides of
the slide just forward of the safety. Pull the slide to its
rearmost position and release it while holding the trigger to
the rear. Release the trigger, a click should be heard and the
hammer should not fall.
Pull the trigger to check the single action. The hammer should
fall. Place the safety in the safe position.
If the safety/function check does not indicate an operational pistol,
the Marine takes the pistol to organizational maintenance or the next
authorized repair level.
User Serviceability Inspection
The Marine is responsible for performing a user serviceability inspection
on the pistol prior to live fire. The user serviceability inspection
ensures the pistol is in an acceptable operating condition. This
inspection is not intended to replace the detailed pistol components
inspection following disassembly or the limited technical inspection or
pre-fire inspection conducted by a qualified armorer. To conduct a user
serviceability inspection on the pistol, perform the following steps:
Ensure the magazine release button is on the left side of the
pistol for a right-handed Marine, the right side of the pistol
for a left-handed Marine.
Ensure the magazine seats into the magazine well when it is
inserted and that it cannot be pulled out.
Ensure the slide stays locked to the rear when the slide is
pulled rearward with an empty magazine in the pistol.
Ensure the magazine falls out freely when the magazine release
button is depressed.
Repeat the preceding four steps with the second magazine.
Ensure the slide is locked to the rear before lubricating
the spring guide, the top of the barrel just forward of the
front sight, and the guide rails of the slide assembly behind
the safety. With the muzzle pointed downward, work the slide
several times and release.
Inspect the pistol’s external parts visually to ensure that
there are no cracks or excessive wear.
Perform a safety/function check of the pistol.
Pistol Maintenance in Adverse Conditions
Combat situations can place Marines in a variety of adverse conditions.
Therefore, the M9 service pistol must be maintained properly to ensure
its continued operation.
Extreme Cold
In extreme cold conditions, ensure that the following maintenance is
performed:
Clean and lubricate the pistol inside at room temperature, if
possible.
Apply a light coat of lubricant, arctic weather (LAW) to all
functional parts.
Always keep the pistol dry.
Keep the pistol covered when moving from a warm to a cold
area. This permits gradual cooling of the pistol and prevents
freezing.
Ensure that a hot pistol is not placed in snow or on ice.
Keep snow out of the bore of the barrel. If snow should enter
the bore, use a swab and cleaning rod to clean the bore before
firing.
Hot, Wet Climates
Maintenance in hot, wet climates must be performed more frequently:
Inspect hidden surfaces for corrosion. If corrosion is found,
clean and lubricate.
Remove handprints with a clean cloth in order to prevent
corrosion.
Dry the pistol with a cloth and lubricate it with CLP.
Check ammunition and magazines frequently for corrosion.
Disassemble and clean the magazines with CLP and wipe dry with
a clean cloth. If necessary, clean ammunition with a dry cloth.
Hot, Dry Climates
In a hot, dry climate, dust and sand can cause stoppages and excessive
wear on component contact surfaces during firing; therefore, keep the
pistol covered whenever possible.
Corrosion is less likely to form on metal parts in a dry climate.
Therefore, lightly lubricate internal working surfaces with CLP. Do
not lubricate external parts of the pistol. Wipe excess lubricant from
exposed surfaces. Do not lubricate internal components of the magazine.
Heavy Rain and Fording Operations
The following maintenance procedures are followed during periods of heavy
rains or during fording operations:
Always attempt to keep the pistol dry.
Drain any water from the barrel prior to firing.
Dry the bore with a swab and cleaning rod.
Generously lubricate internal and external surfaces of the
pistol with CLP.
Amphibious Conditions
If the pistol comes into contact with salt water, clean the pistol
as soon as possible. If time does not permit cleaning in accordance
with Technical Manual (TM) 1005A-10/1, _Operator’s Manual, Pistol
Semiautomatic, 9mm, M9_, then wash the pistol with fresh water.
