Good stuff :-) ... Since I have to have a heat treated slide and want stainless the Caspian is the one I needed

And the 460 Rowland "Kit" is right up there

Below are the technical reasons

There are two key elements to the .460 Rowland concept. The first is a sharp increase in cartridge maximum pressure over the .45 ACP and .45 Super. Maximum Average Pressure is: 45 ACP (21,000 PSI), .45 ACP +P (23,000 PSI), .45 Super (28,000 PSI), .460 Rowland (40,000 PSI).
