Original 460 Rowland 5" 1911 barrel kit that is lightly used. Includes all the parts required to drop in and go. Compensator does a great job of mitigating muzzle flip and recoil. According to Rowland website, it should fire and function with standard level 45 ACP rounds as well, but I only used 460 brass. I will include 20 pieces of once fired Starline 460 Rowland brass to get you started. If you could get one (backordered like almost everything is) they are $330+ from Rowland site. I'm asking $290 shipped.
