It's a marginally decent defense round, but not from an NAA mini-rev, IMO. Those are neat toys, and well built, but they're so small that their handling charactistics and sight radius, etc., lead to very bad accuracy, slow follow up shots, and extremely loud blast and flash for very little return in performance out of that tiny barrel. UNLESS you get one of the black widow ones (or whatever they're called) that have a 4" ish barrel and the larger rubber grip - those are decent defense guns, I suppose, albeit single action only. You'd be much better off defending yourself with a knife than one of the 1 or 2" bbled mini-revs with the tiny grips.
