They shut down their single actions, not sure if forever or not, there is a place on their web sight that says they are re-tooling, also heard a rumor they might make single actions again in 2014. I don't know what they will do in the future.
I ordered some handsprings and got them in the mail already in case one broke, been shooting it and playing with it for about 7 years now without breaking one yet, after giving this some thought I decided to keep it with flat springs throughout. You know how it is, you get to reading things on the internet about people drilling them out for coil springs....I guess I read too much. I figure there isn't any small parts that can't be replaced if it breaks, and I think it feels better with flat springs in it anyway. Tried a wire spring once in place of the trigger/bolt spring, took it right back out, didn't like that either. I hope they make them again someday, USFA's are not cast or forged, they are cut from a solid block of steel. I don't know how many revolvers are made with this process, I don't think very many. I'm going to leave it as is...except for wearing some more bluing off of it.
