*Every* guy? Really? Every single one?
I tried to get my wife to shoot everything from 9mm to .40 to .45. She tried several, from among my handguns and my dad's handguns. She didn't like them. The only gun she like shooting was my .22. She has tiny hands, and - more importantly - nerve damage from a since-replaced disk in her neck that prevents her from maintaining a tight grip. A .380 is the only thing she can actually hold and shoot, that is worth carrying.
So, when we went to buy her a gun, we started with the .380s. She is very happy with her Glock 42, even though I know that I can barely hold the thing, and certainly wouldn't enjoy shooting it. But she does.
More broadly interpreted, every guy in a LGS who assumes he knows what is appropriate for a woman to shoot is a dumbass, whether it be a pink gun, a .380, or an "idiotproof" revolver.
