I just took my brand new G17 to the range. After firing just over 100 shots I realized the small pin above the trigger - the topmost one, which I believe is the locking block pin - was sticking out of the right side of the gun by about 3mm, at least. I pushed it in with a tip of a broken pencil and shot another 50 rounds or so. It feels secure now, but I am concerned that if it worked itself out once, it will happen again. This is a brand new gun, no way that the pin is worn out. What are my options ? Should I give Glock a call ?
