All of them that I have purchased are still functioning properly and I still rely on them everyday. This model is for my Glock 31 Gen 3 in 357 sig. At some time Crimson Trace for some reason seems to have changed the material on the body from a high density rubber type material to a hard plastic that is somewhat rubbery to the touch. Perhaps it is just this model I am uncertain. You may not have the same experience with the one you recieve as I did...but here is my unusual experience. During the installation process where you replace the trigger pin through the grip into the plastic on the right side was a challenge because the product's plastic body was so rigid. I have installed a lot of these and in most cases they are not too difficult to install but even with a drawer full of Glock tools and variety of Glock punches this plastic one was a booger to install without damaging the right side plastic hole. I am not trying to make this a big deal but for novices you MAY need to use patience and be prepared to have a nice punch and or another pair of hands to manipulate the plastic while you advance the new trigger pin. The adjustments to zero was simple. Patience and carefully adjusting at multiple self defense ranges repeatedly until I was confident with how it performed (unloaded) when I tested in live fire this laser was absolutly spot on. The Green Laser seemed not as bright as I expected but it is fantastic in sketchy darkness or foggy/rain conditions making your primary sight hard to see it is excellent. This Laser should never replace your primary sights but in certain conditions this can be a lifesaver. I now hands down perfer the Green over the Red laser now. All my installation grumbling and whining in this review I still give this product 5 stars. I rarely write reviews but this product and the roll it plays in many peoples lives I thought it was worth it. I am buying a 2nd (this model) one today, I ordered mine 12 days ago tested it thoroughly and I am ordering another one for my Son. desertcart was flawless and delivered as promised. desertcart & Crimson Trace - Glock Gen 3 full frame Green Laser - Just Rocks. Update: Today is 7/27/2018. Crimson Trace Green Laser grip for Glock Gen3 is still working great no problems whatsoever. G31 and this Crimson Trace Green Laser has been my non stop primary daily carry. I still recommend both the full size G31 Gen3 with the Crimson Trace with the Green Laser. I favor the green laser as my favorite laser, but still use my other pistols sporting the Crimson Trace Red laser grips. 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. ## 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.

As I said in the headline, great for order eyes. Faster on target and for engaging multiple targets. I have not used it beyond 10 yards so far due to the snow drifts. That will have to wait for better weather. It will light up a target clearly at 75 yards. Only issue I see is battery life, 2 hours. A 10 pack is already orders. I will follow up once I get 1-2 Hundred rounds my model 45. ## Frequently Bought Together - Crimson Trace LG-637 Lasergrips with Heavy Duty Construction and Instinctive Activation for GLOCK Full-Size Pistols, Defensive Shooting and Competition - TOFEIC Grip Frame Insert Plug for Gen 1-5 Glock 17 18 19 20 21 22 23 24 25 31 32 34 35 43X 48 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/45097120-lg-637-lasergrips-with-heavy-duty-construction-and-instinctive-activation](https://www.desertcart.hr/products/45097120-lg-637-lasergrips-with-heavy-duty-construction-and-instinctive-activation) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
