Nope. It wasColt...or Iver Johnson.....it was one of the two.....I forget which.
Python had it in 59'? I will have to go look.
I'm curious as to what you find out. Transfer bars and "hammer blocks" are two different concepts and I don't think Colt (or Iver Johnson) invented or first used (or maybe even ever used) the transfer bar safety system.
Is there anyone who owns a Taurus with the transfer bar system who can't stand this feature?
As others have asked, what about the transfer bar system concerns you in any way? It has little or nothing to do with how quickly (or slowly) the trigger is re-set and the design has been used by many revolver makers over the past several decades without any problem that I'm aware of.
