This holster is designed for a Ruger Vaquero, or similar single action revolver. This is perfect for a 5 1/2 inch barrel, but shorter barrels will work just fine. As with all our holsters this is fully lined with the same leather as the outside for durability and long lasting strength. It has a smooth liner to protect the finish, and for easier drawing and re-holstering. This one is any eye catcher, so be ready for plenty of compliments.
