An idea they obviously stole from Ruger LOL. I've seen more than a few GP100 and RedHawks that had firing pin protrusion as low as 0.030", before being sorted out.
Nah, Colt had used it since 1969 in the Trooper MKIII. I dont think Rugers used it until 1972 in anything. The Security Six came out in 1972.
Again, I have no idea what the new Python design is, just a guess, but if the hammer nose is too long, pin protrusion is going to be minimal to misfiring. If the hand is set by a spring on the transfer bar (like the MKIII and V), that too is going to corrupt function if the hammer nose is too long.
It's about QC.
