During a so-far unsuccessful search for stainless steel crossbolt safety replacement kits, I noticed that one-piece firing pins are available for Marlin M1895s. As far as I can determine, Marlin 336-based rifles have had multipiece firing pins from their inception. I've not detected much grousing about their unreliability -- compared with a similar set-up for USRAC/Winchester M1886s.
1. Is there a significant improvement in cartridge ignition reliability when using Marlin one-piece replacement firing pins?
2. Is there a deterioration of safety factors associated with the multipiece firing pin?
What is significance of Marlin one-piece firing pins?

It's so simple to be wise. Just think of something stupid to say and then don't say it. Sam Levinson

Re: What is significance of Marlin one-piece firing pins?
I use (and sell em) for 1894s. The main advantage is for action games, where ya want an absolutely smooth lever throw, use a LIGHT hammer spring, as well as as much reliability as possible.
The one piece pin does away with that "crunch" ya sometimes have as the lock block aligns the two piece pin. It also requires less hammer effort to fire primers. The two piece pins have been known to fail also.
The SAFETY issue is only when re-assembling the gun. I suppose, back in the day, some IDIOT reassembled his gun without the bolt lock block, fired it, and had the bolt smack him in the face, maybe even killed him. The two piece pin CAN'T fire the gun if the lock block is absent. That's the only thing it does for ya. FWIW, if a marlin has been worked on by ANYBODY, turn it bottom side up and look for the lock block lug where the lever engages it, just behind the trigger. if ya got a big hole there, don't fire the gun BECAUSE if ya do have a one piece pin, yer gonna have a major issue when the gun fires when not locked up.
When I work on rifles, I do so on a clean bench and don't let parts migrate. I am pretty unlikely to forget the lock block. Even then, I LOOK FOR IT once the gun is back together.
