I wouldn't carry any brand of 1911 with a shell chambered and the hammer cocked. Safety be damned. I just don't trust the safety. I have a Kimber I've posted before and I carry it loaded but not cocked. If I can't cock the hammer it's too damned late.

I have shot a lot of Glocks and own a Sig Sauer. I am indifferent to any difference or advantage one over the other in them. Besides, the OP was asking what he should do for his chick and I think the best advice is get her what she is comfortable with and let her work on the accuracy by processing rounds.
