I want to thank the guys at EDM of Garland for helping me out on my custom Glock 19 slide, I had broken a titanium screw while installing my RMR and ended up taking it to a local gunsmith to try and retrieve the broken screw, he ended up braking a carbide bit and also damaged my treads in the process, so I took it to EDM Garland and they were able to help me out by showing me the process that they use and were able to get the screw and bit out without any damage to my slide.Thanks again!
