Your bolt should be machined like the one on the right to clear the Glock magazine feed lips. Even if it’s not it should only hang up with a mag in the lower. Did you fully assemble the bolt stop or just do a mock up? I would install it completely if you haven’t yet.
Bitches make some dudes crazy!

4 arrested in shooting sparked by 'mutual female acquaintance' in Westland
I have 2 9mm builds with them and they really remove the weird recoil impulse in a blowback type rifle. I have a couple in a few 5.56 builds also. You know something works well when they are always sold out.
Adjustable safety, they usually have hex cap screws. If you can’t get it out use a dremel and grind it flush.
Looking at it again it looks like someone replaced one of the two hex caps with a headed screw.
