Just purchased a 1950 CM "as is". It's in great shape finish wise and a little "loose" mechanically. Issue I have is it locks up when at full cock and when the trigger is pulled double action. When the hammer is forward the cylinder can be rotated by hand with very little effort. When in battery the cylinder can't be turned. It's in WA state prison for now but when its released I plan to pull the side plate and give it a good cleaning to see if that solves the problem. With the cylinder open, pressing on the cylinder stop, spring tension seems plenty strong.
