That’s why I keep an exra mag in alongside the 1911 at night, with the LED flashlight.
That’s a total of 16 X .45 ACP. Should be adequate.
At that point, if 16 rounds is not enough, something is VERY wrong — I am in a gun fight, not a self-defense scenario.
Even an 870 doesn’t have that many rounds ;-)
My Saiga holds 20 rounds. :} It sure will be messy.
