Make offer. I've got a like new Uberti Colt Dragoon .44 Caliber black powder revolver. It comes with a Howell Conversion cylinder allowing the revolver to fire .45 Colt revolver cartridges. You will get the black powder cylinder along with a leather holster. I'm asking $550 cash or best offer. The revolver is about $475 and the conversion cylinder is $250. Holster is about $75 value. Must meet in McKinney.
