if it doesn't have ENOUGH morepower than a .22 lr to MATTER any, especially if the pc is bigger and heavier than a Kahr PM9 9mm. The only reason to choose such a 380 is you're too CHEAP to buy the PM Kahr, and you're DELUDED about blowback 380 "power". Shoot some chucks, *****, etc with it. Watch them run off, JUST like they would with a .22 hit in the same place (most of the time). Don't even THINK about using it on big dogs, cause you'll get your ass chewed, real good.
