It seemed like a lot of my friends were real doubters about lasers on handguns back when they first appeared. I shot an S&W 59 at a range with one and soon ordered one. I only have one surviving pistol laser now, a center mass one on my SAR CM9, the rest of the cheapo ones I bought died for one reason or another. It's almost impossible for me to miss with one as long as I can see the dots (There are 6 in a ring, and one in the center). I bought several of them on closeout at $25 a pop and I guess I'm going to break them out and stick them onto a few of my railed guns instead of saving them in case the one on my CM9 died. It's had a couple of thousand through it and neither the gun or the laser has had any issues.
