The Mepro FT Bullseye Sight was designed to fit most standard holster designs with no adjustments, allowing the shooter to just install the sight on the slide and hit the range. The Mepro FT Bullseye is drop-proof and shock-proof, built for endless rounds under heavy recoil. The ultralight, snag-free design is easy to draw and enables instinctive aiming under pressure. This family of sights gives you one serious advantage above all else: they are always on and always ready.
