Century has been really great regarding a few issues I've had. No complaints with them at all. You just need to give them a few days to respond.
They sent me the reduced power spring but I never used it. I went to the Sprinco and now running a SIG with 1911 spring or the Glock tungsten extended. IDPA doesn't allow tungsten rods for added weight. I should be getting an 11# variable power Commander spring in a couple days to try. It shipped yesterday.
The SIG is the cheapest way to get a rod that allows you to change springs to tune to your loads.
