SS, how do you think you would have come out - if the shooter hit you with .45ACP, .45LC, .44Mag, .40 S&W, .357 Mag, .38 Special, .380ACP, 9mm... ?
Had anything other than .22LR been used, I don't think I'd be replying to you right now, brother.
Sounds like you're going to rely on this .22LR pistol for self defense, because it LOOKS like a familiar, larger caliber handgun. If you're planning in intimidating someone with a handgun, then you're carrying for the wrong reasons.
Also, you're not training with a .22LR handgun alot lately. Not unless you stocked up on ammo about 1.5 years ago.
