Hi CALREB !!
That 4566 is a beauty!! Thanks for sharing it with us.
I'll have to settle for one of the production models for my carry gun. I had my PC 4566 CQB sent off to S&W this past February. I had Novak night sights installed and a spurless forged hammer too. It is going to be my "last duty pistol".
I just got it back yesterday and I'll be starting a thread on it. Thanks for all your advice CALREB!!
slfree, one way to SOMETIMES tell is the serial prefix. S&W used a PCZ prefix on many BUT NOT ALL prototypes.
Any of you other fellas have some pics of your S&W 45 prototypes? Grinder??
