Abstract: A rapid and adjustable sighting system for pistols includes front and rear spring clips, which may be easily and removably attached to the existing front and rear sights of virtually all conventional pistols. The front sight attachment includes a generally U-shaped spring metal clip, which may be secured to the front sight of a pistol by glue, soldering or pinning, for example. Pins with various sized and colored heads may be selectively mounted on the spring clip to provide the front sight. A second spring clip, also of U-shaped cross-sectional configuration, is similarly attached to the rear sight of a conventional pistol, and includes a central recess for receiving spring plastic rear sight inserts. The plastic rear sight inserts are generally circular, have an upper sector of about 60 degrees to 140 degrees removed from the top of the plastic insert sights, to provide an unobstructed view of the front sight and the target.
