SIGHTS
The purpose of sights is to assist in aiming the piece. The national
organizations allow only “open” sights in pistol and revolver shooting.
“Peep” or “aperture” sights are barred. The rear sight usually consists of
a notch shaped like a V or a U, the notch being as wide on top as at any
part. The front sight is a piece of thin metal set on edge. Sometimes the
latter has a special shape or section resembling a pinhead when looking at
it from the breech, as in aiming.

Military sights usually consist of a plain groove in the top of the frame
for the rear sight and a tapering front sight fixed to the barrel near the
muzzle.

Target sights are made in endless variety to suit individual ideas. The
sights most generally used for target shooting are the “Paine” sights,
named after Chevalier Ira A. Paine, who invented and was the first to use
them. The rear sight is a flat bar with a semi-circular notch, and the
front sight is a “bead” sight; that is, a sight that resembles a pinhead
when aiming.

Patridge Sights.]
Another sight that many of the best shots are using is the “Patridge”
sight, developed by Mr. E. E. Patridge of Boston, Mass. The rear sight has
a wide rectangular notch; the front sight is plain, with a square top, as
shown.
Fig. 61 represents the “Lyman” sights as adapted to Smith & Wesson
revolvers. The distinctive features of these sights are the ivory bead of
the front sight and the horizontal ivory line in the rear sight. These
sights are well adapted for hunting and shooting at objects with a dark
background.
These sights have been referred to in the order in which they are most
used. It is generally necessary for individuals to try various sights
before they are able to select intelligently. In target arms
different-shaped sights may be used in the same base or fitting, so that
it is a comparatively easy matter to try any or all of these sights on the
same arm.
The notch of the rear sight should have a bevelled edge concave toward the
front. This will secure sharpness of outline in any light. The front sight
should also be distinct and is found to be more satisfactory when the side
toward the eye is a surface at right angles to the line of sight.

For years means have been sought to make successful shooting at night
possible. White and phosphorescent paints have been applied to the sights
and to the top of the barrel but all such methods have proved more or less
unsatisfactory even in dim light and in total darkness the target or other
object cannot be seen. A recently invented device that overcomes all these
difficulties and makes shooting at night practicable is the “Wespi”
searchlight sight.[10]
This sight is a tube about 6 inches long and ¾ inches in diameter
containing a miniature electric searchlight which projects a dark spot in
the center of the illuminated field. When properly mounted on the piece
the black spot indicates where the bullet will strike. This sight can be
readily attached to any pistol or revolver. As offered on the market at
the present time it is adapted for short range work up to, say, 60 feet.
The illustrations show a section through the sight tube, and the sight
attached to a revolver. The weight is six ounces. (See 61 and 62 facing p.
64.)
This sight embodies the principles of the telescopic sight and can
undoubtedly be modified to increase its illuminating power and adapted so
as to project well-defined dark lines similar to cross wires, on a
target; or the dark spot decreased in size to about 3 or 4 inches in
diameter at 60 feet. So modified this would be a practical sight for
target shooting and would be a boon to many of the older marksmen whose
sight is failing and who find it more and more difficult to shoot in
artificial light with the ordinary sights.
Such a sight would also possess many advantages for beginners as the
moving spot on the target would indicate the unsteadiness of the holding
and impress upon the marksman the importance of holding the spot in the
right position at the instant of discharge. A further improvement would be
to substitute for the dark spot, a spot of intensely bright light. This
would be equally as effective as the dark spot and would greatly increase
the range at which the sight could be used, adapting it to game shooting
at night. It is hoped that the manufacturers will develop a sight as
suggested for target and game shooting.
