So you're basing your argument on "usually" and "might?" :rolleyes: I'm not trying to be rude, but come on. ANY mechanical device USUALLY works for it's intended purpose, but as with anything it MAY break, no matter if it's Taurus, S&W, Les Baer, Chevy, Ferarri, Mac, PC etc etc.
No, it does not hold 15 rounds, but again, 15 misses or a jam because you limp wristed it (or your wife did it) are also not good. If it was a home defense, I am shooting close range gun, I do not feel under gunned at that point. Would I like more rounds? Yep, and that is why it is not a carry gun for patrol.
Oh, and at least a revolver usually shoots with every pull of the trigger barring misfires and that is an ammunition thing in most cases.
