Can anyone recommend an ANC/ valley smith with Glock experience?
I have a KKM barrel that is giving me fits (pun intended) in a G20SF. It is not reliably returning to battery about every third round or so. When hand cycling, it appears to fit just fine. I tried smoking the barrel, looking for contact areas, but I can't narrow it down to the problem area. I'm ready to throw in the towel and give it to a pro.
