Enough for what?
Good Point above, for work I have one in the mag well and 5 in pouches, but 2 mags are 75 Tap and two 55 Tap and two in FMJ 55. Running around in the woods on the 4 wheeler 2 or 3 mags tops. SHTF you cant have enough. Plus they are mechanical and do break down, so keep in stock a couple of rebuild kits to repair. Mark each one, I use numbers to keep track of them and know which one it to fix if it fails. dont forget to try all of them, dont keep using the same ones.
