FWIW:
I live in the country in SE Ga.. The chances of my running up on a "gangbanger", or criminal of any type where I live are very slim.. In fact, my chances of running up on a rattlesnake (in summer) is about the only threat I have concern about.. Even then unless you step on the critter it'll just slither off..
I'm an old fart, and in my advancing senility, I just try not to kill things anymore.. There was a time when I would drive 50 miles with my 12ga. High Standard Pump riot shotgun to shoot a rattlesnake, but now, unless it's in my yard, I would probably just let it go.. Of course if it scared me I might shoot it just because.
Having said that we do have numerous "feral coke cans" in the woods hereabouts. So when I'm out walking in the woods, (or my wife and I are out on the county roads in her golf cart) I always take along my Firestorm FS22.. It's a nice little PP/PPK lookalike, surprisingly is very accurate, and so far extremely reliable. I just load up 10+1 rds of WW's cheapest value pack ammo, and I'm good to go.
This sucker is deadly on those attacking coke cans....
Now, when I'm out of my personal comfort zone I carry either my Walther P99c/AS (9mm), or my Sig P239 w/CT Lasergrips, or my S&W 638 Airweight Bodyguard, also w/CT Lasergrips. I have absolute faith in all three, and if it's in the daytime I like the P99c/AS, but if low light or nightime conditions prevail I prefer one of the Crimson Trace Lasergripped firearms..
Best Wishes,
