I put one on my Glock 19 and it works pretty well. I'll include some pics so you can see what it looks like. I probably wouldn't do it again cause I got another laser for my XDS and its a green laser and there really is no comparison between red and green in bright sun light. The green wins hands down every time. Once you use green your spoiled.

"Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." C.S. Lewis
