Tested icing editing okay so i fired 100 PCM 115grain today and had one not fire, I notice the hammer dropped to a half cocked position. It never stroked the firing pin. 1911 half cock position it stopped at. My guess, look picture. Is it has the beretta 92fs and bobcat21a, trigger bar system, appears to fail, or when you fire you release too quick and causes problem. Just theory for FTP in the sig p938
I still trust it for carry, only one problem in 100' and 4 in 350 rds
