Ruger Bearcat. Made for woodsbumming and will outlast your grandchildren.
Excellent, I like that one. I've got one I like a lot that fits this description, a Rossi M68 with a 3" barrel. It's very accurate and I can carry .38 wadcutter or +P depending on need. The wadcutter is very accurate and shoots to POA in the gun for small game and such. The +P is pretty accurate, too, and only shoots a bit higher. This is my go to for the woods bumming scenario and I can even pocket this gun in a few pairs of my pants, 3" barrel and all.
A Smith or Rossi (I have a M511) kit gun comes to mind, but for something a lot smaller and easier to carry, how about a NAA Mini Master? I've often thought this little 9 ounce .22 would be fantastic in this role. It's single action, but then so is the Bearcat.
I have a little pocket Phoenix Arms HP22 that is very accurate and fantastic so long as you ain't gonna be relying on it for self defense. I wouldn't do that with any .22, though. It's tiny. I made a wallet holster for a rear jeans pocket to hold it. I've shot rabbit and snakes with it.
Just about any snubby .38 can handle the role well. I'd go with an airlight/airweight gun for the pocket. If you're going to go heavier, for IWB, the SP101 is okay, but I sure would prefer an adjustable sight. I'd go with the 3" gun. I wouldn't worry about carrying a .357 unless you have big cats in your woods or bear and then I'd prefer my medium frame 3" .357, myself. But, just for the possible dog attack, humans, utility for small game and such, a 3" .38 fills the bill for me in the form of the little Rossi. It'll shoot 2" 5 shot groups off sandbags at 25 yards with wadcutters. That's pretty useful afield and the .38 is plenty of caliber around here. Now, when I'm down at my place, I carry a .357 because I might see a hog, but there are no bear or any threat from mountain lion or anything around here. I've come upon gators, but I can't imagine ever having to shoot a gator in self defense. I guess it could happen if I stumbled on a nest in spring, but I've never heard of such a thing happening and I don't swim with gators so they're not a threat. The only REAL threat to me in my bummings around are humans and perhaps a pack of wild feral dogs. Dogs can be vicious, much more of a threat than a wolf or something. I don't have any love for feral dogs. The only good one is a dead one.
