Just picked up another 150 rounds to run testing through mine in two weeks. I fired 250 rounds (see review I made) and only had 2 FT-FIRE with 115grain. I had 2-4 FT-FEED/jams with 7 round extender magazines.
We have to remember these are small pocket guns, they can jam, and have problems more so than thicker,heavier,bigger guns.
SHTF vs TEOTWAWKI you ask? SHTF, just some crap on the ceiling and walls, TEOTWAWKI end of the world as we know it. Orignally made by 9mm/®™©
