I have taken a break from my endeavor. I have sold, locally, my G21 for $700. And, I have replaced it with a Taurus M415 41 Magnum. I plan to, eventually, buy an LWD G21 slide, threaded barrel and a Yankee Hill Machine 45ACP compensator and get back into the .460 Rowland game. But for now, I will just enjoy making lots of noise and flames with my 41 Magnum.
Good luck to all of you guys jumping on the .460 Wagon!
