Personally I don't know why people insist on making the 410 something it's not. Just because someone gets the idea to chamber a pistol in a round doesn't instantly qualify it as a self defense weapon. The 410 is a small game/target round, that's it. I don't want to hear your stories about deer hunting with it, just because you can doesn't make it a good idea. The 410 as a self defense round is weak at best, especially when shooting it from a 3" barrel, I don't care how you dress it up. It could shoot posion darts and it still would be a weak SD round.
If the pain is lacking so is the discipline...
