Damage on Model 22 Im seeing a gouge and a deep scrape just ahead of the serial number tag inside the frame on the left side near the muzzle-end. Ive used a generic scope mount on the guns front rail for target practice with an aimpoint type sight, the mount is actually too tight for the rail and had to be fitted. The mount might be binding the lower frame near the muzzle end. Ive installed a Lone wolf barrel that extends beyond the slide by 1 inch. I also have a sider lock trigger safety because Im a wimp. After I noticed the problem Ive also installed a Scherer guide rod inside the sleeve of the plastic guide rod to reduce flexing. I dry cycle the slide and Im feeling a bump as the slide returns to battery position just near the damaged area on the frame. The binding and gouges in the polymer appear to be advancing after practice on the range so Im wondering if its time to call glock.
