I didn't want to taint my recommendation by saying I own a Bersa but the fact is I sold a Colt Mustang and bought the Bersa (actually a Firestorm model) with the money and am very happy I did. The Mustang was a nice gun but was 4"-5" groups at 10yds while the Bersa is more like 1-1/2".

Also the sights are much better and it has the hammer-drop safety which allow it to be carried fully loaded while the Mustang requires the 1911 style cocked & locked mode I doubt she would be comfortable with. The only negative feature is that it is a little bigger than a lot of the popular 380s being sold now but then she has a purse to help her conceal it. The Sig is just a clone of the Mustang. Both are way overpriced IMO.
