I'm pretty sure I broke the firing pin on my Single Shot Inc high wall. I need a source for a new spin as well as disassembly instructions. My book says to remove the hand guard to get to the main spring. Not on my rifle. There is a real fancy spring wrapped around the hammer, block pin etc. I'm afraid to drift out the lever pin without consulting someone familiar with the action.
Thanks, Old Soldier

I have 3 of these rifles, and have broken the firing pins on a couple of them.  I found that if you place the hammer on the safety notch before opening the action, you greatly reduce breakage.  Now to your problem.  I have never seen one of these rifles with a hand guard.  I think you are referring to the forearm, which would have to be removed to get to a leaf mainspring.  These rifles have a coil spring.  To remove the firing pin, remove the firing pin retaining screw in the top of the hammer and the pin falls out.  If C Sharps can't sell you a new one, I can tell you how I repaired mine.  wyoold

Wyoold is old, so he mispoke, just like a politician.  Of course, I meant the breech block. Sorry.  Wyoold
