AmeriGlo brings a clear advantage to your shooting experience on and off the range. The Hackathorn Sights/ Protector Sights are designed for quicker front sight acquisition and concentration on the front sight blade. The black, serrated rear sight reduces glare and offers assistance in one-hand slide manipulations, while the front sight offers a tritium illumination and a ProGlo outline in LumiGreen or orange for an enhanced aim point. Ideal for any conceal carry or personal defense weapon. Not compatible with Gen5. Does not fit Glock MOS slide.
