Beavertail for RMT frame?

[Icefire]

I bought a 1911 in parts for a project (Chromed 1911 in .40, with great quality)

It's an alloy frame and the place where you put a grip safety can't be radiused for regular .250" beaver. (or do I just suck and it could be?)

Drop in would be nice. It's a RMT frame btw, pretty rare.

Here's a pic:
