+1 on the 10 shot S&W. I had a chance to buy on years ago and didn't, I have been kicking my own butt for years for not. They aren't that common, probably because folks that have them KNOW what they have. Fantastic revolver to do ANYTHING a .22 is suitable for. For a S/A, the Beretta tip up barrel, I forget the model number is a neat little gun, and it is a damn sight better than a stick or a rape whistle if you MUST use it in a defensive capacity. I know everyone is going to tell you that a .22 is no good for defensive carry, I know that they aren't perfect, and I'm sure you do to, but if that's what you can afford and it is what you have, I think it is better than nothing. Getting shot friggin hurts, and no one likes to leak.
