I'm having issues with my 312 I am trying to restore. It came to me missing the hammer so I bought a replacement on line. It looks just like pictures and drawings of a 312 hammer but the spring and trigger suggest something is wrong. I think it might be the wrong diameter for the 312. My barrel end at the hammer side is 13/16 by my measure and this hammer is 3/4 leaving a good amount of slop that I think is causing the issue. Can anyone with a legit 312 tell me the right diameter of the larger end of their hammer for comparison, and if 3/4 is too small, where can I find the right one?
And yes I'm aware of the hammer wear issues that can be caused from safety wear. But this isn't that. This hammer has a goid sharp lip on it and no signs of wear but I think the trigger can't engage well because the hammer can move over to the other side of the barrel and that's why I have a hair trigger. Also the bolt pull back suggests the spring isn't compressing straight in alignment but instead is bending in a curve for the same reason. I'm sure the hammer should not fit as tight as the end cap, but believe it should have less slop than it does.
