I was inspired by Joe's three part series on how to convert a 1911 to 45 super for $8, so in May 2000 I converted a 20 ounce patriot pistol form 45acp to 460 Roland loads with 45acp brass.

The manual on the pistol said no +P but the factory supported me and gave me lots of parts. The pistol was designed by Nehemia Sirkis. I don't think he was around when they were helping me.
