Maybe i used the wrong term in describing "frames" what i have is a ss blackhawk that i got in the 90's It was a 45 long colt.I had a smith make me another cylinder in 45acp to fit my blackhawk. I also have a couple of old model vaqueros in 45 colt.That 45acp cylinder will fit in the old model vaqueros and the blackhawk.what I am trying to finnd out is if the new 45acp cylinder and frame is of a different size than my older guns.
YES. The "New Vaquero" 45 ACP birdshead model is the mid size frame. So no, your 45 ACP cyl ill not fit, it's .060" larger in diameter.
The current production "Vaquero" (44 Spl only) and "New Vaquero" are made on the mid frame size. The only exception is the brand new 44 Mag. "Vaquero" soon to be released as a Talo distributor exclusive model.
