I have not read all replies and posts prior to mine.
That being said, IMHO, This is destined for total failure.
My wife decided on her own to train, and then purchase her "class" pistol, and then later, her carry pistol, and then later, several itinerarations of the "right carry pistol for her".
First criteria: the pistol or revolver that fits right in their hand. Then there are many, many other evaluations for THAT PERSON to detrmine.
It's like picking the right purse, shoe, carry knife, or other thing for your spouse.
In my situation, I gave my input from time to time, but ultimately the selection she made was based on what she herself did felt was right in her strong arm grip hand, what felt right when actually firing it, follow up shots, when racking it, when holstering or un holstering it, best fast sight alignment for her, easiest for malfunction drills, most natural to her for reloading, etc., etc,., etc...... among many other variables.
Those are a whole Lotta variables that the non carrying person of that particular firearm, cannot possibly decide for someone else.
My wife has lots of firearms training and far more self defense training than me and most on this forum have , but what I think is a great carry gun for me and most others, simply won't work for her.
