Controls are the same as a 1911. I would think the extra weight would help to tame the recoil, although .380 has very little in the first place. Kimber probably has an aluminum frame and the Sig is steel?
The SAS looks very similar to the Kimber as well.

The other choice I had for her is a .327 magnum.
