My wives over the years have liked a variety of guns. My ex, liked Ruger 357's, especially the Speed/Security-Sixs. She wasn't a slouch with a Government Model 45 Colt either. And I know it's not a handgun, but that woman could smash clay pegions with a Remington 1100 in 12 ga all day long....POOF smoke in the sky.
My current wife has used a Glock 19, a Smith & Wesson 65-5 Ladysmith 357, and her current carry gun is a Charter Arms Lavender Lady in 38 Special.
In short women have different taste, same as men. They enjoy it more when they pick for themselves. About all we can do is advise.
