Too tight for the 22/45 thread protector. - Tactical Solutions Pac-Lite MK Series Holster

Holsters are limited for the Mark II/III 22/45. This comes with one adjustable rubber grommet retention screw. I’ve loosened it to the point that several threads are exposed in the nut, and I’m worried that it’ll works its way out. Even this loose, I use too much force to shove my pistol home. The interior ribs that hold the barrel hit the factory thread protector. But when its taken off, it fits perfectly.

Because there aren’t many holster options for the MKIII 22/45, I’ll keep it and sand away the interior ridges that hold the barrel in place.
