Neither Para nor Kimber are known for their high-grade small parts, although Kimber sells a pretty fair frame/slide/barrel kit.
The 1911 was designed to be made out of certain materials to certain tolerances, not to be assembled from a range of plastic, cast, and MIM parts made to a wide range of tolerances by eleventy different subcontractors.
If I was planning on spending less than ~$1,100 or so on a gun, I'd go buy a used Glock.
Seriously. I have watched real spare-no-expense 1911s get built from the bare frame up. I know how much work goes into one. I know how much the parts cost, even in bulk.
Ironically, if you are planning on leaving the gun stock, you might be better off with a Filipino slag gun or a homely Brazilian than a midgrade domestic piece since I believe the former two do all their small parts in-house. They may be sloppy and cheaply-made, but at least they're consistently sloppy and cheaply-made, unlike the midprice domestic gun where the small parts are often coming from whatever outside vendor had them cheapest this week and the pace of production means not enough time can be spent on individual guns to compensate for variations in tolerances.
