Crimson Trace LG-637 Lasergrips with Heavy Duty Construction and Instinctive Activation for GLOCK Full-Size Pistols, Defensive Shooting and Competition

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.

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.

This is a great product. Fits my pistol perfectly. Everything is included to install it, and installation is easy. I'm far-sighted, so this is a real help when acquiring a target, up to 50 ft., as advertised. I'm very happy with this Laser grip. 5 stars.

Had an issue with the laser not consistent on activation. Contacted customer service to explain. After providing them with the information they required the sent me a brand new unit. Can't ask for better customer service and standing behind their products.

I really like the addition of a laser to my Glock 17, Gen 4. With my left eye good for distance, and right eye good for close up, it makes for a blurry sight picture. The laser is vastly better for my needs. Installation instructions were a little vauge in regard to proper placement of 2 shims, lower shim lacked any adhesive, so it fell out several times when I tried to slide the laser grip in place over the back of the pistol grip. Glock provided two different replacement pins for securing the laser to the grip, but did not explain which one you should try first. And in the case of the pin that had both ends reduced in diameter, did not explain which end should be inserted first. Also I was disappointed to see that the batteries, switches and electronics were not provided with any waterproofing. I expect the laser will quickly stop functioning if it is ever used in the rain or other wet conditions. I rated this product high in value for your money because it has been discontinued on the CT website and is on sale for only $162. I'm expect they will soon come out with a better/more expensive model, but for now this on is adequate for my needs.

Might be a slight hassle to install, depending on which gun you have.Leaves the accessory rail open for a flashlight.Easy to sight in. Makes aiming a lot faster.Makes my girlfriend feel more confident.

Love it had to adjust it a little but works great easy to adjust.

Perfect fit
