You would first need the barrel you want , the extractor rod would be an issue, they vary on barrel lengths. So the center pin and rod would be an issue. After that , the new barrel would need the barrel-cylinder gap trimmed ( .004 would be perfect ) anfactory d the forcing cone may need to be deepened. A serious gunsmith if the could do all of this. Check Alan Tanaka in Gardena, CA. The factory used to offer this but who knows if they can pull this off now. Gun's and Gun Parts in West Springfield, Ma.
may have a barrel for you if you can not purchase direct from factory.
Good luck, KCOMP
