How does the wife feel about the Glock?
Would she prefer something else?
I suggest that for the wife, let her select what she wants. She is more likely to carry "her" handgun than a "hand-me-down".
I would not give my wife my old motorcycle helmet (even if it was the best I ever had), as it may not work for her. And so goes my belief on her handgun.
