Crimson Trace LG-637G Lasergrips Green Laser Sight for Glock Gen 3/4/5 Full Size - Black Polymer

The Crimson Trace LG-637G Lasergrips add an instinctive-activation green laser sight to your full-size Glock pistol without permanently altering the factory frame. Designed specifically for Glock Gen 3, Gen 4, and Gen 5 full-size frames including the 17, 17L, 19, 22, 23, 31, 34, 35, and 37, these Lasergrips install as a replacement backstrap on the existing polymer frame, wrapping the grip in a rubber-overmolded panel that activates the laser the moment the shooter achieves a normal firing grip.

At the heart of the LG-637G is a 5mW peak Class 3R visible green laser with user-adjustable windage and elevation, producing a 0.50" dot at 50 feet for fast, intuitive target acquisition in close-quarters and low-light work. The beam is rated to a 50 ft range, more than adequate for defensive handgun use. A rear-activated pressure pad built into the backstrap preserves Crimson Trace's signature Instinctive Activation feel, so there is no external toggle or button to reach for under stress.

The unit runs on two CR2032 lithium batteries (included) for approximately 4 hours of activation time. The rubber-overmolded polymer panel installs in place of the factory backstrap with no permanent modification to the firearm. Built around a black polymer chassis with a soft rubber overmold for positive retention, the LG-637G is water-resistant and ready for everyday carry or duty use on your full-size Glock.
