A warm gun. Duh. 119 RA45T through it today plus 50 UMC and 50 Federal ball. No malfunctions. Even loaded it to 15+1 with the defensive ammo, ran fine.
Well, I need more pistol trigger time. If I did my part, it shot fine. If I didn't, well, blah.
Added: I can still feel the stippling over an hour later. Considering the callouses on my hands, that is very impressive.
