    Ruger has changed the profile of the Ruger Mark pistol firing pin. These firing pins are no longer a "stamped, die-cut" part. What we will now be receiving is a CNC precision machined firing pin that is 27% lighter than the previous offering. For those who think it may be important, "lock-time" will be that much faster than with the heavier firing pin.


    The tip has a more "chisel point" configuration that concentrates the force from the hammer spring onto the rim area that's more efficient at detonating the primer mix.


    I've tested one new firing pin in two Ruger Mark II & one Ruger Mark III to see how this firing pin performs. Below is a random sampling of some of the spent cases that were dug out of the snow bank they landed in.
