I have seen many 1911 grips free floating around. You might want to download a few and just cut them. See how it works, learn from the file how the toolpaths are created and go in and modify the design and i think you will learn more from doing that rather then starting from scratch and not getting it right then getting flustered.
I have learned a lot that way because someone has already done it right and you can see how they did it.
