The Beretta is a ridiculously large gun for the round it fires and the amount of ammo it holds. You can get a Glock 19, which still holds 15 rds of ammunition, has a shorter barrel, a grip that isn't as fat and awkward, and doesn't have that God-awful frame mounted safety-decocker.
As much as I dislike the Beretta, I do have to say that I haven't had one that I've been issued ever jam, but because of the crappy magazines the military INSISTS on buying, the ones I've used have hardly ever gone to slide lock.
