It is what it is. I bought one for goofing around with. It has given me no problems. The trigger is a bit stiff. I haven't shot much 45colt out of it, but it seems to shoot to POA pretty well at seven yards. It is fun to blow up old cans and veggies and so forth out at my BiL's place out in the country. I did not buy it for SD. However, as far as I can predict from shooting it, 3" magnum 00 buckshot at close range, say ten feet away, would be effective.
IMHO, the salespeople who tout it as the greatest SD handgun ever and the critics who say it is useless are equally inaccurate.
