I have been shooting a Victory model in 38S&W. I have others and have dedicated this particular revolver to shooting. I would like to know if I can change the hammer to a .375 inch hammer of a more recent production, and are the springs interchangeble to lighten the trigger pull with the more modern K frame revolvers? I have ordered springs from Brownell in the past to lighten the trigger pull on a couple more modern revolvers and wonder if those K frame springs will work in a 1942 revolver.
