There is a little keltec PF9 I think in 9mm parabellum. It is a nice little package with 7+1 hollow points you can take care of any dogs and crocks
if they show up.
it is a 9mm in a 32ACP type of package.
The gun I defended myself with against the chow was a kel tec P11, 11 rounds on tap of 115 grain +P at 1263 fps avg for 10 shots. It only took one round on a 70 or so lb chow. He turned and ran howling off to die at his owner's, later, the one who called the law on me. I figured I was in the right and TOLD the cop I shot the dog to which I was disarmed, arrested, and booked. I later got the gun back after the case was thrown out.
See, thing is, you kill a man, you get a grand jury to rule whether the case is even worthy of going to court. You kill a dog, you get arrested and have to prove your innocence, which I did, just sayin'. If you're going to kill something, kill a human. You can get away with that. Dogs have more rights than people.
I mean, we had a leash law in that town, that dog came into my yard and attacked MY cats and when I started kicking the snot out of him, he attacked me. I didn't have a ball bat or anything handy, only my daily carry. Now, I have the pepper spray along with my two carries 24/7. Yeah, I learned the hard way, I guess.
BTW, it's legal to defend live stock from dogs and I grew up in the sticks where we had lots of feral dogs I've had to shoot. Shot every one of 'em with a .22 rifle and don't remember any getting away. It don't take a cannon to kill a dog. It's the Indian, not the arrow. A .22 works fine if well placed. If you can't shoot a handgun, maybe a Taurus Judge???? Pepper spray in town against attacking dogs, though, is ALL I'll recommend from my experience.
