My wife is unable to keep a BG or LCP properly on target due to the long, heavy trigger. She also could not rack the slide on either very well / at all. She's 29 and fit, so it's not like it's an arthritis or lack of strength issue. Granted, she does need help opening jars but she can rack the slide on other guns.
She went with a Sig P238. Larger, but best for her. Far superior trigger, manual safety, and the slide is easy to rack. Single action only though.
In all my years shooting (and thousands of rounds fired), I've only encountered one center fire round that failed to fire the first time but did the second... meaning second strike isn't a requirement for me. I personally prefer to clear the round immediately instead of trying another trigger pull.
Also, she finds the P238 much more manageable as far as recoil is concerned. She actually enjoys shooting it.
I have a Kahr CW380 which she can keep on target better because it is striker fired and the trigger pull is manageable for her. However, the slide is just as hard for her to operate.
Best bet, try to get a BG in her hand and let her get a feel for it. I owned an older style BG and liked it for the most part.
