I have a 1966 (I think) python that I was going to rebarrel. I have read that there are two different barrel threads for python barrels. Does anyone know how to tell what barrel thread you have and when it changed?
"The old style Python barrel threads are .5634-32 threads.
These old style threaded barrels are identified by having TWO pins in the front sight."
"The new style Python threads are the same size as the Trooper Mark III/King Cobra.
These threads are .562-36 threads.
These new style threaded barrels are identified by having ONE front sight pin."
