This is a Springfield MilSpec that I 'Loaded' myself over a period of years. I asked a local (and nationally recognized, I might add) gunsmith about the 'loaded' models, because frankly, for the dollar I don't know if you can get a better production 1911. He was aware of my Mil-Spec modifications and put a seal of approval on them. Here's the interesting part. When I installed the beavertail, as you may already know, the Springfields have a .220 radius on the rear tangs as opposed to the .25 radius found on most other 1911s. That limits your parts selections a little bit, but Brownells has most or all of it. But he then told me that the 'Loaded' models, by his measurements, have and even tighter radius and that if replacements parts were needed, the ONLY source was Springfield. Food for thought
As I said, for the dollar, the loaded is a very nice production gun. The next best deal is an STI, but that brings the price up several hundred dollars.
