Stick to all 9mm. I would do a Glock 17 with a BUG Glock 26. 4 mags on weak side. Regular mag in the 26 and a +2 in the 17.
thought I was different with 2 magazines lol.
Just get the 50 A.E that round is 3x the size of 45acp
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/®™©
