Firing Pin H&R Model 1900
I am trying to remove and replace an old Harrinton and Ricardson Model 1900 firing pin that fails to withdraw back into the receiver. This is one of the early guns. While most have a screw on the top of the reciver to hold the firing pin in, mine is internally accessible.
I am suposed to be able to access the screw by removing the trigger guard, which in turn is held in place bu a screw that is almost accessible if the breech locking lug lever is tuned all the way to one side. Still, I cannot quite get a straigt shot at it with a screwdriver and am thijnking I may need to grind the side of a driver down just a half inch from the edge of the blade.
I am going to attach a couple of pictures.
The bottom picure is a git deceptive as the barrel locking lug retracts further so it is flush with the face of the breech block.
Does anyone have any suggestions?
