If you are looking for a chest holster for your gun I would like to recommened the Elite Survival Systems HN45BL. This company formerly known as Survival Systems produces outstanding holsters. The HN45Bl will fit Rugers single and double action up to a six inch barrel. If you do not mind that the barrel hangs out 1/2 inch it will also fit the 6-1/2 Blackhawk. The best is American made, low price and that the holster is always in stock instead of having to wait 2-3 month .
