Most Pro mag reviews I seen are junk. Mec-gar makes some of the best for the 92fs. I have some that are 17/18? rounder and they make 20 rounder (extended) But my 17/18 round magazine is nice, has numbers on all holes.
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/®™©
