Is the hammer loose on the tumbler axle, or is the hole through the lock too big for the axle?
The axle moves the tumbler when you manipulate the hammer. The hammer is tight to the axle & doesn't move around when under the strain of the main spring (cocked). Does that tell me the lock plate hole has been enlarged from use? I would be surprised - its the left hammer and both barrels are cylinder choked. I don't think its been dropped on the hammer - no scars & mint. It's a .44 caliber shotgun & in excellent condition. Half of the color is still there & the twist barrels are about mint also (I think original). Its the lock plate hole isn't it, dang'it?
