Anyone have any experience with the cheaper one that are like $179 vs the screw on ones's that are $100 bucks more. I was going to put some on my glock 27, I just didn't knowif the cheaper version stayed sighted.
I've got the $275 set on a S&W 642 and like them. I don't know about the cheaper ones, though. I looked at a set for my G27, but decided against it because it adds too much bulk. I'd rather go with the Lasermax.
