A phosphorescent sight system is provided comprising a rear sight for disposition along a proximal portion of a slide substrate of a firearm and a front sight for disposition along a distal portion of the slide substrate. The sight system may further comprise an optical waveguide disposed within a waveguide cavity of the rear sight or the front sight. Further, a phosphorescent element may be disposed adjacent a proximal portion of the optical waveguide.

An open sight for use on weapons such as handguns is disclosed. The open sight features two rear aiming marks mounted in the rear sight and a third aiming mark in the front sight. The aiming marks are illuminated by one or more artificial light sources disposed within the rear sight. The artificial light sources project light forward to the front sight and illuminate the rear aiming marks. The front sight is dimensioned to substantially block the forward directed beam to reduce the visibility of the illumination forward of the weapon.

Optical sights for mounting on a firearm are provided, each of the sights having a base defining a barrel end and a rear end; a frame extending upwardly from the base at the barrel end and defining an opening; an optical element received in the opening; and an illumination device operable to display an aiming point on the optical element to generate said aiming point.

A reflective gun sight includes a rear sight including a light source; and a front sight including a reflective surface that is directly opposing the light source and recessed within an aperture of a front sight housing, wherein light emitted from the light source travels through the aperture and is reflected by the reflective surface toward the rear sight.

A rear sight is provided for use on a firearm. The rear sight includes a changeable and removable rear sight notch insert. The rear sight further includes a rear sight blade having a cavity configured to receive the changeable, removable rear sight notch insert. The changeable, removable rear sight notch insert includes one or more tabs to facilitate insertion or removal of the rear sight notch insert into or out of the cavity. The rear sight notch inserts are variable in notch width, notch depth, and notch shape.
