So I bought a used Taurus revolver a while back chambered in .357 magnum. I've been carrying it concealed, and for the most part I'm very happy with it, but I've had an intermittent problem. Randomly, usually after I empty the cylinder, when I reload and try to pull the hammer back, the hammer will be stuck. The trigger won't pull either. There seems to be a pin that should be getting lifted or placed somewhere by some mechanism, and it's visible when you open the cylinder. The only way I've been able to restore functionality is to take a thin blade that fits in the slot behind the cylinder and press the pin back and up while working the hammer. Eventually it re-seats itself where it's supposed to go and the gun will work just fine again for a while. Below is a photo of the pin in question. Right now the weapon seems to function normally, and I can't really tell anything different about the way the pin is positioned when the hammer locks up. Otherwise the weapon appears to be in great shape, shoots accurately, rifling doesn't have any noticeable pits or chips, etc. Usually after I load it for carrying, I pull the hammer back one time then ride it forward to make sure it's functioning, because I've only had the hammer stick immediately after reloading. Excuse the dirt, I literally just walked in the door from shooting it and haven't had a chance to clean it.
