Featuring instinctive rear activation, a rugged build, and easy user installation with adjustable windage and elevation, it offers 4 hours of continuous runtime powered by included batteries. This grip sight enhances defensive shooting and competition readiness while fitting seamlessly into existing holsters, all backed by a limited lifetime warranty. ## Description LG-637 Lasergrips® are a rear-activated laser sight for GLOCK Full-Size pistols (Third Generation 17, 17L, 22, 24, 31, 34, 35, 37, Gen4 17, 22, 31, 34, 35, 37 and Gen5 17, 19X, 45). Featuring Crimson Trace's famed Instinctive Activation™, which allows the laser to be activated with a normal firing grip, the LG-637 includes a Master On/Off Switch for completely powering down the unit. User-installed in moments by attaching securely to the gun frame, this laser sight is fully adjustable for windage and elevation. Provides 4 hours of run time with (2) included 2032 Lithium Batteries. Review: Save hundreds on holsters by using this grip-sight! !! - An accurate and compact laser sight specifically for certain 3rd generation, large frame Glock pistols. A major benefit of the grip-mounted laser is that it usually allows the continued use of existing holsters without modification. Because the sight mount is molded exactly to conform to the 3rd gen frames, it is securely held in place by a replacement trigger pin, metal replacing the factory plastic trigger pin. Installation takes just minutes, but read the directions carefully. There are TWO included trigger pins, some fit one version of the pistol-sight combinations, the other pin is used for a different combo. DO NOT FORCE THE FIRST PIN, IF IT DOESN'T FIT, USE THE SECOND PIN. The sight is easily adjusted by minute modifications to laser mounting, using the included small Allen keys. Review: Accurate. Activates on grip. No special holster needed. - Easy to install. Easy to use with one hand. Easy to align - although comes pre-aligned at 50 feet (for home protection use 30 feet is probably best - but the difference is small). Don't forget to apply the delivered inserts when I stalling on 17-G5 and 19x-G5. ## Features - BRIGHTNESS: Features a 5mW peak, 620-670nm, Class 3R visible red laser that is in conformance with and complies with 21 CFR 1040.10 with a max power output of 5mW for a Class 3R Red Laser - the brightest beam allowed by law - RUNTIME: 4 hours of battery life that runs on (2) 2032 batteries (included) - EASE OF USE: Rear activation button engages the laser immediately when the firearm is held in a normal firing grip - this model features a master ON/OFF switch for completely powering down the unit - user installed - no gunsmithing required - RELIABLE: Factory sighted at 50 feet, but is fully user adjustable for Windage and Elevation with provided tool - FITS: Glock GEN3 17, 17L, 22, 24, 31, 34, 35, 37.

I have a Glock 19 Gen 3. Does this meet your full size gun definition?** A: No, the Glock 19 is considered a compact. The equivalent laser for your gun is the Crimson Trace LG-639G. **Q: is the grip thicker because of the 4 batteries? also, does anyone know how it fits the G31 gen4 .357 sig?** A: No. It actually fits my hands better...just reall hard to get one side of the grip pin to align. Grn is BRIGHT! **Q: Does this fit glock 45?** A: No - .45 ACP Yes - .45 GAP (model G37 only) **Q: Does it fit a Glock 17 Gen4?** A: Yes it will fit the gen 4 glock 17. Hope this helps.
