The LASERMAX Laser Sight For Glock 20/21 (LMS-1151P) is the most rugged and reliable laser sight on the market, as well as the only completely internal laser sight gun currently available.
Whether you are a law enforcement professional or a civilian, LaserMax Laser Sights are designed to improve aiming speed and increase accuracy. The internal laser means it cannot be knocked out of alignment, while it remains easily removable when needed.
Fully compatible with grips and aftermarket accessories, the LaserMax Laser Sight drops easily into place and replaces the original recoil spring guide. An ambidextrous switch, custom take-down lever, a pulsating beam for increased visibility, and deliberate on-off activation make the Laser Sight easy to use. Factory aligned with quality assurance, the Laser Sight comes with a three-year warranty.
