Except that the slide on the CM is shorter. The slide of the CM+sight block is maybe 1/8" longer than the slide on a TS.
I just weighed the TS and CM that I have. The TS was 44.2oz and the CM was 42.8oz. The TS has a decent amount of grip reduction and thin grip tape grips and the CM has the extended safety and lemon grader grips, other than that, they are the same. The point I was getting at with the slide being shorter/lighter is that there is less reciprocating mass, which is the actual important part. Hence why slide lightening is so popular.
Shot a CM for a while then go back to the TS, that is where you will notice the difference.
