[Col.Colt]

That's a real coincidence and you have a 1941 to. What is the difference in the firing pins how do you know which one your gun requires?

What is the difference in the firing pins

The original one was round profile and could break at the front causing a slam fire, out of battery...so they changed to the commonly found half flat profile. Mine had both included when I originally bought it here in Canada back in about 1976 and it took some years before the internet told us about the possible problems. To read up on a case of one that went high-order, you could read Pyle's book on the Gas Trap Garand and a rifle that was found in the rafters of the barracks in Hawaii. It was fired until it went to pieces and it's suspected the round firing pin caused it.

If you take yours out and it has a half flat profile, you're fine. Unless your rifle is a time capsule, you likely don't have the round firing pin.
