Hey Peak -- I share your regard for JMB, but, IMO, his last design was his best. 15 + 1, half-cocked and locked.
As for the Sigs, there's good, better & best, in 9mm, 45Auto, and 40S&W. The upright style, grip contour, size, weight and balance, for me, are perfect. But I can see how a petite young lass like yourself might prefer the 1911 :emoticon:
PS: I guess this is an armed hijacking of the OP's thread.
