No, it has no change in uncocked and cocked, or trigger pulled in double action to cock.

Toolguy, I'll go measure the end shake now, and post the results. But it's more than just front to back movement, it has side to side rotational movement as well, but I think that's ok. It doesn't move enough to get the cylinder out of line with the barrel and forcing cone.

I've just never seen a revolver didn't have some lockup/tightening up with the hammer cocked, and aren't sure if it's ok and is just inherent in this cheap revolver, or if I need to send it back to the manufacture for repair.
