Just got back from the local gunsmith where I had previously left my G36 slide and a pair of Glock Factory Night Sights. They looked great on the weapon and I was very excited to go home and put it all back together. Well... Now the factory barrel wont properly fit into the slide. It sits about 1mm from where it is supposed to go. I'm bringing it back to them tomorrow as soon as they open to have it fixed. I'm just wondering if this is a common thing. Right now, I have it narrowed down to two possibilities: 1. The front sight is mounted too deep into the weapon, is obstructing the free passage of the slide, and needs to be adjusted (I hope it is this simple) 2. My slide got bent in the vise when they were mounting the sights Any thoughts? I guess I'll find out for sure tomorrow... Wanna kill these ads? We can help!
