I got a little old Uggie Falcon and cut it down for my son, I believe they are an A&D action. When I took it out to try it tonight it doubled every time I fired it. Right barrel first, left barrel first it didn't matter. I did have it apart to replace a broken hammer spring, but nothing else was broken and I didn't do anything other than that. I can't get it to do it by striking the butt to simulate recoil. The only thing that I can think of is that maybe I have the hammers swapped right to left so there fit to the sears isn't correct?

I will tear it apart tonight and see what I can find but was wondering if anyone could offer any insight?

Thanks,
