I can't seem to find much on this subject as to running 45 super or possibly using Clark's Customs 460 Rowland kit in a E Series 1911.
I'm curious more towards the 45 Super as I have been contemplating using it in my 625 revolvers. It seems that most people change the main spring, recoil spring, firing pin stop, and possibly the firing pin spring to successfully convert a standard 1911. I was wondering if the same would apply to the E Series with it's external extractor. Some also say to upgrade to stronger magazine springs as well.
If you have ran 45 super in a E Series 1911 reliably, could you help me out in converting mine? Thanks!
