While I like the concept, unless it's the new version that takes the more powerful shells, it's useless with the .410 as a personal defense weapon. .410 out of short barrel picks up so little velocity and has so little power it will barely penetrate skin. I'm not saying I want to get shot by it, but it's 5x more useful loaded up with the .45, which will put a hurt down on somebody. Using a .410 with them, it also has the tendency to "wad" the lead together by the time it leaves the barrel, so it's all one big malformed hunk flying unpredictably through the air. I'm not trying to be negative and talk down your purchase, but I do want you to know that if somebody is on meth and you shoot them with the .410, it probably won't incapacitate them, but it for damn sure will scare the heck out of them and the wound it leaves will look MUCH worse than it is, and put them in panic mode.
