What would make you chose one caliber over a different one for cc .Barrel length 3 in to 3.5 max. Same pistol 9mm,357 sig .40 sw & 45acp. Add revolvers in the question 1 7/8 to 3. max, 38 sp,357 mag ,44 sp ,44mag.& 45 acp.. With all of the ammo mfg .making sbl ammo. what's your choice ?
Is this all same weight?
Because the choices would always be aruged. If you could get a 9mm in the same size as a 44 mag? people would fight over this topic non stop, you would need a book or something to write about.
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/®™©
