Patridge Sights.
Figure 60.
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.
