I used to have a little Belgian made Browning .380 auto that was a cop's backup gun originally. I never shot a deer with it, but I put holes in several sharks up to maybe 200 pounds at boat side with it. Also shot a couple of alligator gar with it, but it would not penetrate the skull of a 120 pounder I caught. Carried it in a shoulder holster while surf fishing at night after getting in a scary situation one night without a gun (no sharks involved), and had it with me several other times when it made me feel a little safer. It fit in my front pocket and was completely concealed. Never had to fire it for defense, which is the best kind of defense gun.
