My SS .45 Bisley is one of the first lot without the .45 ACP cylinder. While I really like using the .45 ACP cylinders in the .45 Colt revolvers, I don't mind too much with this one. I prefer the standard NMBH grip to the Bisley grip.
I just got my SS .357 NMBH back. I had them change the 4 5/8" barrel to 6 1/2" and they added a SS 9mm cylinder. I haven't yet shot it. It will be interesting to see if the 9mm capability is worth anything.
