I would like to second Lost Sheep. If you’re going to beat a 1911 that hard take some advice and get a recoil buffer. They are cheap and will increase the life span of a 1911. And maybe stop a frame from cracking .
I own one of the Ruger convertible Blackhawks in 45 ACP and I have loaded some hot rounds in ACP but the gun was so inaccurate it was a total waste of time.
