ruger mark 1 bolt assembly

[dirtybronson]

I have a ruger mark 1 that seems to be having weak primer strikes and not firing all the time. Suspect new bolt assembly may fix this issue. any information on this would be appreciated, ruger has stopped making mark 1 parts. thx

Is the firing pin in spec? Should be able to source one of those out. WGP, brownells..
