Yes. The one she likes.
See my previous post about Darlin' Daughter and her choice to go with the Glock 26.
She also shoots and likes my Browning Hi Powers, but she doesn't get those until after the reading of my will. Unfortunately, while the BHP is a favorite of many women I've know or heard about, they are no longer in production, so the ones out there are very expensive (as in you can buy 2-3 Glocks for the price of 1 BHP), so I can't really recommend to someone starting out. (It's one reason I went to Glock after decades of carrying a BHP)
And if the guy behind the counter starts pushing her to small J Frame revolvers or other small "cute" guns without her having tried them on the range, smile nicely, walk away and ignore everything he's told her up to that point. She may find she likes those guns just fine, but she shouldn't make a purchasing decision until putting at least a box of ammo through it on the rental range. J Frame revolvers are NOT beginners guns IMHO, and the recoil from them when shooting defensive ammo has turned many off shooting altogether.
