The FN 510 Tactical answers all your handheld autocannon needs! The pistol ships with the flush-fit 15-round magazine like the one in the photo, as well as a 22-round(!) 'stendo, just in case your position is about to be overrun by a fire team of mutant undead ninja grizzly bears.
If it can't be solved with 22+1 rounds of 10mm Auto, it's probably not the sort of problem that can be solved with a pistol in the first place.
