If your set on a Springfield, I'd go with the loaded target also for the front serrations and adjustable rear sight included, as mentioned above. I do use front serrations in competition at ULSC, and the adjustable rear sight is nice for adjusting to your reloads. For competition only, I wouldn't worry to much about the MIM parts, as long as you dont start trying to go home 'smith on them. If you decide you want to start making changes beyond adjusting springs, sure, by a good ignition set then. And the accuracy from the factory should be plenty for SS; cant say I'd spend the money on a new barrel.
