I stepped up to a Man's cartridge -- 460 Rowland! Here's my G21L with 24# Wolf Spring and LW Compensator that I put together today: (yes - photo taken before I drifted in the rear sight) Results of todays range time with a Chrony: 185gr Gold Dot Underwood Ammunition = 1630 fps & 1091 ft/lbs 230gr Gold Dot Underwood Ammunition = 1430 fps & 1044 ft/lbs Definitely 44 Magnum territory! With this long slide (solid top), 24# Wolf Spring, and LW Compensator -- it felt like target load 45 ACP Ball when shooting the full power 460 Rowland. Shooting ball through the pistol without changing anything felt like 22 rimfire... Wanna kill these ads? We can help!
