I been trying to get my slide milled and get some type of reflex sight on one of my Glock slides for a while. I had one RMR found dang cheap but after having 2 tires go bad on my car I just couldnt get it at the time. I stumbled across a guy that also had exactly what I wanted "I think" locally and I had something he needed as well so I was able to pick it up without putting myself in a bind. Im not completely done with it but its close enough for now. Same slide 2 frames. One for shooting and fun and the other for carry. I know they are ugly but they are tools. Tools that work perfectly for what I need.
