There was no "for me" metioned in what I originally quoted.
As for the rest they are all designed and built from John Browning/Colts original work.
Now, out of curiousity could you post pics of the differences of your two 1911s? I think it would be extremely helpful to the OP and anyone reading this thread. The last RIA I saw had the worst factory barrel fit I'd seen outside of a Llama so I'm curious to see the differences aswell.
