I'm thinking a 1911 that can throw down like a 44 mag would be an awesome blaster. The cool thing is you can still shoot ACP for those lightweight days.
I think the brake is the trick in making these work. When I built my 357sig I added a panzer brake on the end of the 9" barrel. Between the weight on the end of the barrel and recoil reduction I could barely get it to cycle"Do Not Exceed " loads. I eventually lost the brake and cut the barrel back to 7" and it functions with everything. I'll probably get back around to it in the next year or two if I get some money to blow and don't build a Colt Walker Rifle for something entirely different. My 357sig is pretty badass ringing steel out to 200yds with Lehigh's going 2,300fps.No, but I shoot one on a Springfield Armory XD-M. Turns your semi automatic into a 44 mag equivalent. You need a much heavier magazine spring which makes the magazines really hard to load. Mine has a locktited compensator on it and a different recoil spring, so it's not an easy switch back and forth between 460 Rowland and 45 acp.
