Do you want the gun to shoot or to look at?
I shoot mine. Yes, I do have some guns that are collectors, that are all original, etc. But they are pieces of art and are more for looks. (Yes they are pretty. I shoot the ugly ones !)
If you got the gun to shoot, and do want to shoot it, send it to TC with all of the barrels. They will make sure all of the barrels and the frame are working together for you. They will likely install all new springs, give it a major tune-up and send it back with no charge. You will have a shooter, not a collector.
Good Luck with your choice.
