Durabledan, Welcome to the forum! First question to you: Did you have the gun apart and do anything to it or has this "problem" just come up suddenly? One of the first things I would look at is the hammer dog operation. It sounds like the trigger extension that lifts the hammer dog is jamming up somehow. Take the hammer out and check for damage and free movement of the hammer dog, hammer dog plunger and spring. look for burrs and debris that could be impeding trigger or hammer movement. Check these things out and then give us a report!.....................Dick :wink:
