Otto,
I don't think it did have an independent system to withdraw the firing pin(other than a spring), otherwise I suspect you could see some sign of it.Since it is necessary for the pin to be no longer than the breechblock, it is also necessary that it be withdrawn(in some manner)for the striker to hit it.Making the rear of the pin protrude more would increase the speed, therefore inertia,as would a stronger mainspring.While I'm not one to modify these older rifles,sometimes it is necessary when the original system would fire original ammo, but not modern.Of course this assumes orginal ammo can't be reproduced or it's not convienent to do so. My Mod 71 Mauser would not fire modern primers(even pistol primers), until I replaced the mainspring with one that was much stronger.I have not had a misfire since." If at first you don't succeed, get a bigger hammer".
