NO, NO, NO.
A "ladies gun"
of the era, particularly one given by a man as a gift, would be a nickel plated, pearl handled .25 auto. Everyone knows that a woman can't handle anything more powerful, anything bigger isn't going to fit in her purse, and she's just going to use it to "scare off" the bad guys anyway.
Everyone who is suggesting the double-action only Centennial is forgetting how weak women are. That's why the Centennial is so safe - with the grip safety and DAO trigger, only a man has the strength to operate one. Heck, you could leave one fully loaded lying around the house, secure in the knowledge that women and children would be unable to fire it.
Also women are only going to want something shiny and pretty. It would be an insult to give a woman a blued gun. My vote is for a nickel plated, engraved Baby Browning with real mother-of-pearl stocks. That's the closest thing in the firearms world to jewelry, and would go well with a woman who drive a Cadillac.
Or so would be the thinking of the time.
