Armalaser tr5 - ArmaLaser Red Laser Sight for Glock

I really believe, for the money spent, you can't go wrong with this laser. You just need to be patient when installing, and read the directions. Don't force it and adjust it by what it says. This was for my girlfriends 380' she has fired many rounds down range and it keeps its alignment. But for someone with big hands like I have, it maybe a little difficult to activate, she loves it...
