One of the things that was always attractive about the FN Five-seveN (other than that it makes Paul Helmke a sad panda) was the ammo capacity. I’m a firm believe in the “more bullets is better” theory of gunfighting, so if I can have a gun that holds 20 rounds, I would. Hence the large magazine on 5.7x28mm gun was appealing – until I bought a Springfield XDm. 19 rounds in the mag + 1 in the pipe make my desire for a souped up .22 Magnum dissipate entirely. Why rely on a weird novelty cartridge when you can pack 20 rounds of 147 grain JHP?
