FA specs show this at 35.5 oz (1/2 oz more for octagon bbl). Mine was bought used and I've shot 25,000 to 30,000 rnds (most rnds I've ever put thru a revolver). It also has an auxiliary 45 ACP cyl. Shoots "Ruger Only" or standard 45 Colt loads (ACPs w/aux cyl). Five shot, small frame (basically same size as Colt SAA). Downside - PRICE.
