Hey guys I have an infinity slide on a custom open gun I bought used. Regardless 8,000 rds in i head a clunk while cleaning the slide, come to find out the breach face was loose and the reason I didn't notice it earlier was due to the firing pin holding the breach face screw with a little tension when it was fully together. Once I removed the firing pin, it very clear there was foward and rear ward slop in the removable breach face.
Took it apart and cleaned the threads, firing pin tunnel, slide face, extractor tunnel after removing the extractor... I then put it back together (with out the extractor, and with out loctite) just wanted to see what I was dealing with before I when on with it.
After assembling and snugging up the breach face screw/beach face there was still a significant amount of slop in the breach face... so I ordered a new 9-L breach face from infinity and screw. Installed it today when I got home and still had the same amount of slop. Looks like the hole in the slide it's self is wallered/worn out a little.... so efff me.. my only other option is to try and tap the removable breach and make the threads go a little deeper in the breachface in hopes to snug up the screw to the slide. (In the removable breach face there is still room to go a little deeper. I do not know why infinity use a tapper tap vs using a flat bottom tap and going all the way to the firing pin hole. I'm sure they didn't expect the slide hole to Waller out..) do any of you guys know what thread pitch a removable breach face screw is for an infinity slide? Thanks guys, this is my attempt so save my self 1500$ in fitting a new slide with cuts and all the bells and whistles.
