Leave it alone! Since this is a woods bumming gun, not a CCW piece, length doesn't make much difference.
If the barrel length is uncomfortable, try an new holster or three, a good cross draw would probably help if the barrel lenght is causing carry or seating problems.

P.S. Cutting the barrel and refinishing it would run you a hundred bucks or more. Save your money. Either keep it as is or trade it for one that fits you better. LMH
