Thanks again, all very interesting. Obviously bigger slugs are superior, but I went for the rapier vs the cutlass as it were. To me the gun is an easy-to-reach equalizer---for the unlikely, rare situation where I might need to threaten deadly force. After all, how many gunfights are there in the US? How often do citizens actually brandish, much less use the weapon? I decided on a front-pocket gun that's unobtrusive, easy to reach, and something I could afford to extensively train with. I understand the ballistic limitations of .22, but it seems to me an equalizer I know well in my pocket is way better than one I know less well. Unless you're pretty well off the bigger slugs are expensive---rather rich for my tastes. As for the "panic" comment, I have seen reports that even trained users often stumble and fumble in test live-fire situations: if you're being charged, there's just no time. And if there is time, with a cool nerve you brandish, warn, and if necessary pop 8 rounds in. 7 or 8 Velocitors should make anybody take some notice. So of course, go with it and enjoy those huge cannons, but my point is, my little PT-22 is nothing to sneeze at and gives excellent reinforcement should I need it.
