5lasermax laser sight
By kmyers3
I love the sight, it is very bright at night and it shines for a very long distance, it pulsates in a very good size spot on the target. I am not happy that it does not show very well doing the day time out doors, but more than likely I would probably be using it indoors and at night anyway. I love it and I would highly recommend it to my freinds,I especially like the fact that it is internally mounted inside the gun so that it doesn`t get knocked out of alignment.

5Excellent Product
By cmmps
I have only shot 25 or so rounds but so far I am content with the product. It installed easily as advertised and works as expected. I did not have any misfeeds as I did with the Glock 19 version.Accuracy seems good but I was not dead-on with my shots; that should come with practice. My plan is to get a vise to verify the accuracy claims.I like the fact the laser is a natural part of the gun. It is easy and natural to turn on and off. Overall, I really like the product and would recommend it.

5Nice!
By RainierFan
Be sure and read the instructions instead of watching the YouTube videos for installation if you have a Glock 21. Otherwise you might leave a critical piece out.I just wish this came in a green laser option. It's very hard to see any red laser in bright sunlight.Customer service was excellent!!!!!
