A member who is no longer here, was kind enough to let me shoot his personal sidearm.
5" 1911, turned into a 460 Rowland via Clark Customs and man... was that a beast. I got to shoot two mags out of it, and it made my hands numb. They were the light weight "johnny's personal carry" sold by Clark Customs. Specs below.

After being in contact with Clark Customs on the phone and consulting them. I sad what piece I was looking for and they concurred, citing their preference for the brand and for the Carbon steel, not stainless frame, and that it would be a great choice less one part... The firing pin needed to be replaced.
Tonight I ordered my Springfield Range Officer Operator, Tomorrow, I will be ordering the Clark Customs kit.
Photos will be posted as parts arrive. Only parts that I plan to swap out at this point are the grips for Hogue wrap around and the firing pin, per the recommendations of Clark Customs. (they recommended the pin change not the grips)
