My dad has a USGI 1911 that I will inherit. It's a nice shooter. It's parkerized. I'll have to get more specifics.First of all, if you want an "American history" 1911, you should just buy a WWII 1911 or maybe one of the CMP 1911s. New production 1911s are purely commercial products.
My experience with 1911s is that none of them run the way I want out of the box, and I wind up swapping springs, parts, etc. to make them work like I need them to. That's been true for $2000 1911s as much as $500 1911s. Personal opinion, but at the ~$1000 price point, BUL's 1911s are kinda hard to beat unless you have very specific requirements like an optics cut and/or accessory rail.
