It would not fit gun correctly or activate after installment.

My review is the same above. I love my other CTC grips, but LG637G would not fit correctly on my Gen 4 G17 and would not let it activate. I was not a huge fan of the shim idea. As much as these grips cost you expect a little better craftsmanship. It is way to to tight of a fit, the pin wouldnt line up or work correctly after installment. I will not purchase another one until Crimson trace comes out with a better make or mold/ model for the Gen4 G17. The laser is plenty bright, but useless if ineffective on your weapon. Dont waste your money or time until they can correct the issues.

Love the beam, loath the placement.

Pros - The beam is very bright and easier to see in the day than the red beams. I never had a hard time seeing my red lasers in the day time though. The activation works fine. The feeling of the grips is not as awkward as I thought they would be and are adequately comfortable. Overall this is a quality product. Cons - A big problem I have is that the laser sits high and gets in the way of racking the slide when grabbing in an over the top fashion which is very disappointing. They really should look into lowering the laser out of the way of the slide. The Gen4 and Gen 5 need to be shimmed which I am not a fan of. In rating this product, I am taking into account the respect I have for the company and the quality and excellent customer service they have always delivered.

Fits after knowledable intervention

LG-637G Review #2 While the LG-637G grip still is far too tight IMHO, I finally was able to communicate my problems with the grip to a B. Coker, who worked with me and came up with a solution described below. My words, not his. Final result is I dropped one star because it took so long and three destroyed products to get a workable result. Change Installation Instruction 2. To: For safety and ease of installation, field strip the pistol and set the slide/barrel/recoil spring assembly aside. Change Installation Instruction 6 to: There are two replacement trigger housing pins. Throw away the plain one with only one reduced diameter end. You will be using the replacement pin with the diameter reduced for 1/8” on one end, and 5/16” on the other. Insert the shorter of the reduced diameter ends from left to right, blah blah, blah, stopping when the replacement pin encounters resistance on the right side of the new LG-637G grip. Note that the pin does not align correctly with the grip hole on the right side. To obtain alignment, you will either 1 (according to several CT sales people) need to press the front of the pistol grip against something solid like a work bench, or 2 (according to what I did) use a bar clamp compressing the rear of the LG-637G at one end, and the front of the trigger guard at the other, until the pin can been see clearly in the hole on the right side of the grip without touching the diameter of the grip hole. Then and only then, press the replacement pin further to the right until it is flush with the right side of the grip, then release the bar clamp. You will note that the replacement trigger pin is a small circle inside the larger circle of the original hole, rather off center and jammed to the front. I let this set overnight and found there was no fissure of the grip. Whether this will hold when I start firing the pistol…..

Does not fit the gun

The grip is far too tight resulting in the right side of the grip fissuring upward from the pin hole. It did this twice for me, and the third was a gunsmith - same problem even with his doing some interior relief which resulted in poor contact with the button. This grip is just flat wrong for the Gen 3 Glock 22. Save yourself time and money - look elsewhere (at least until CT gets this right).
