I have very little handgun experience but have a specific application that I was hoping to get some help with. I'm wanting a very small handgun to keep in my backpack for the purpose of finishing off a mortally wounded animal. Principally, coyote, hogs and whitetail. I have had numerous occasions where I had to blast a critter at point blank range with my 30-06 or 22-250. Not a pleasant or pretty sight. Was thinking of anything from 22LR to .380 but again, this really isn't my cup of tea. Would like to spend the least amount of $$ possible but reliability is a must. I'm fully aware that we often get what we pay for . . . anyway, please chime in. Thanks in advance!
