I bought one a few years ago and 3 out of the 10 shots wouldn't fire everytime so I had to send it back to s&w. They replaced the crane and some other stuff I don't remember what all they had to do to it. I bought it brand new, it may just be in my head but I don't think it was as accurate when I got it back as it was when I sent it off but it shoots 10 out 10 shots now lol.
