polymer 1911?

A 1911 frame is way more complex than, say, a Glock frame. The Glock fire control group drops in as an assembly; the equivalent parts of a 1911 reside in individual cuts and holes. The Glock was also designed with the section thicknesses appropriate for the grade of plastic they used, which would make them awfully thin for a 1911. If you make them thicker, you change the look of the gun substantially. Also, instead of simple sheet metal rails like the Glock, the 1911's beefier rails would need to be machined, and there's not much room to anchor them inside a plastic shell.

I'm sure you could make a work-alike 1911 frame, but the difference in strength of materials would make it very different in detail. Also, you're talking about some serious tolerance control, shrinkage allowance, etc. to do a 1911 in plastic. The Glock has almost no critical dimensions on the frame; for all practical purposes, it's just a blob of plastic. Production-wise, the Glock is much, much simpler than a 1911. I'm sure JMB would have approved; he advanced the state of the art quite a bit single-handedly, and if any gun designer ever stared Progress in the face, it was Browning.
