As there is with both frames & even more so with trigger stirrups.................that's why there is a tool for shaping them.

Far more likely one of the above than the mags, IMO & IME.

Trigger Stirrup Tool


Agreed, it's a possibility. Though, I did have my pistol looked at by a gunsmith who builds custom 1911s. Since we were able to find quality magazines that work and fit very well, we left it at that. I just didn't expect the KimPro and McCormick mags to drop out as if they were catapulted out of there and the one Wilson that needed to pounded on to get it to fully insert and the others that needed to be dragged out of the pistol. Clearly the Wilson mags had the largest outside dimensions of all the magazines I tried.
