MC 1911 is spot on. Barrels on your revolver are interchangeable with all 15-2 revolvers, including the new ones. Factory lengths are 2", 4", 6", 8", 10", 12" and 15"; although the last three are hard to find. EWK offers parts and specialty barrels and shrouds that aren't offered by CZ Arms (the current owners of Dan Wesson). Dan Wesson offered several different grip styles. Hogue and Pachmayr also have grips.
