I have one, and have mixed feelings about it. Take this with the fact Ive only shot one box of 45, 2 box of shot and a few boxes of slugs and a box or 2 of buck.
the 45 seems to shoot ok decent enough for defense purposes, simply put if he is far enough away that im going to miss, I can run away. dangerous game is a different situation and wouldnt trust it so much.
the slugs, for some reason they are crazy accurate out of mine. very confident with them.
buck shot was ok, not great but for defense its better than nothing, ie I wouldnt want to be on the business end
shot, very short range, good for snakes ( one reason why I got it, that and its hard for me to turn down a .410) rabbits, would have to be pretty close. used 4,6,9 shot.
Overall Id say its a pretty fun gun to shoot, its a niche gun. If I sell it, I wont weep a tear since I dont have a real use for it anymore, but for now itll go out to plinkin range for a little bit of fun.
Id definately shoot your buddies before you buy, it may not be what you want, another thing, alot of the negative feedback is from folks that dont own them, because they see no "useful purpose" for them, as well as most of the possitive stuff is marketing (as a defense handgun), the truth is somewhere in the middle.
I got mine because it looked fun and found a reason for it, not to stop carjackers. up to you to decide a "useful purpose"
good luck
