Just took my Gen 3 G21 converted to .460 out on Sat. for some shooting tests. With 12gr. (MAX.load) Longshot behind a 230 XTP got an avg. of 1345 fps. 11gr. of Longshot was 1305fps.
Fed my homegrown hardcast hardball .45 ACP loads without a hitch. I really like the way the gun handles recoil with the comp. .460 loads controllable, .45 ACP loads are like shooting very light target loads.
Glad I made the decision to go .460 on my G21. I now have 3 guns in one. .45ACP, .45 Super, and .460 Rowland.
Really like the options this offers.
