Ruger's Blackhawk Convertible model includes two cylinders that can be interchanged without the use of tools. The patented transfer bar mechanism and loading gate interlock provide an unparalleled measure of security against accidental discharge. Its cold hammer-forged barrel results in ultra-precise rifling that provides exceptional accuracy, longevity and easy cleaning. The Blackhawk has ramp front and adjustable rear sights along with traditional western-style, hand-filling grip.
