TeenJed, You are correct, I misread your posting and I apologize for my snarly reply
. This is my take on hot rodding a Hawes .45. Ruger made their reputation on how strong their guns were " over built ". I had the opportunity to talk with a Ruger engineer and he informed me that the only difference between the 44 mag and 45 Colt frames were 1/100 bigger hole in the 45 colt cylinder. Same steel, same heat treatment, same every thing. I hot rod my .45 Ruger but I never exceed the loading books. Now, did Sauer and Son go to the extra expense of building their .45 Colt to the same standards as their .44 Mag. Remember they were in a price war with both Colt and Ruger and the 44 mag runs at a much higher pressure and requires a stronger cylinder and frame than the .45 Colt . I don't know and I don't know of any way other than destructive testing to find out. Me myself and I will assume the reloading manuals know what they are printing when they print " Ruger and rifles only". The Rugers are a known entity , The Sauer is a good gun in the same strength category as the other clones of the era { excepting the Rugers } I don't know for a fact they are weaker but until someone proves other wise I will take it to church that the Sauer .45 Colt frame is not as strong as the Sauer .44 frame. I could be wrong, I'm pretty sure I've been wrong before in the past and will be wrong in the future
