1873 firing pin not pushing the hammer back far enough to cock

1873, 3rd model, when working the lever the firing pin is not pushing the hammer back far enough for the sear to cock the hammer, as you close the lever the hammer will follow it back down.  If I press down on the firing pin when cocking the action the hammer will catch in the position to fire.  Not 100% sure what the problem is, the hole in the back of the action is sloppy?  Firing pin bent?   I looked inside and did not see anything obviously wrong or broken.  Suggestions?  TIA.

Ken,

The slot in the hole on the back of the receiver may be the cause. How much play is in the firing pin when the lever is full forward by wiggling it up and down.  Post a picture from the side showing the hammer and firing pin when full open.

The picture shows the lever fully open but the hammer is not cocked.  It is almost like the firing pin is a little short.  I do not feel a lot of flex but if I put downward pressure on the firing pin while opening the lever it will cock correctly.  With the hammer cocked and the lever opened I can see a little little light between the hammer & firing pin.

You need a new firing pin. Some bubba filed the bevel too far forward.

The bevel should look more like this.

Thanks.  Looks like the firing pin is out of stock but on the list when they return.  Since the original pin has already been bubba'ed I might try and drop a bit of weld on the pin and try and reshape or glue on a shim.
