LaserMax designs and manufactures the world's only totally internal Laser Sight For Glock 20/21 w/Finger Groove Rail (LMS-1151PFGR).
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.
To activate the laser, simply push IN on the switch, which replaces the slide lock. Pushing in from either side will turn the laser on; the middle position is off.
Factory aligned with quality assurance, the Laser Sight comes with a three-year warranty.
