Rated 5 out of 5

Excellent product. Worth the investment.

I am new to pistols. This product really helped me to learn correct sight picture on my Glock 45. After taking several professional courses and obtaining CCW Permit, having the laser provides me great comfort to 1) acquire target quicker and 2) increase accuracy should I ever to need weapon for self defense. Cost of product is very reasonable considering peace of mind and better use of ammo.

Best laser site ever

I originally purchased this in 2006. I spent some time dialing it in but once it was set it stayed solid on target. I am using it on my Glock 17 / which is a real workhorse and gets dropped from time to time. I have never had to go back to the adjustments for any correction, it stays put and never drifts, can not say this for other sites from other manufacturers. Not to mention I have never had to change batteries, so there is another plus. As far as usage, I typically go through 200 to 400 hundred rounds a week, so it gets beat up and used a LOT. Stu
