Very, Very Nice addition Padwan. You have done well!!
I am far from an expert on the 1911 platform, and I am okay admitting that.
I do not honestly know, for sure, in that platform if you can change out the guide rod for a single piece full length one. I believe that you can, without any hassle, but I do not know that platform well enough to say for sure.
NGIB or Cane will be along shortly to confirm one way or the other.
Really well done brother. A very nice addition for sure.
