You might consider encouraging your wife and/or mother to rent some try-out handguns at the local range and shoot them before making their decision about buying any particular gun.
Most of us have bought some guns that we didn't try first.
Then, later, many of us have wished we had.
Renting-to-shoot is a good way to try out a prospective handgun for size, fit, recoil, trigger, caliber, etc., etc., etc. before making the permanent commitment to buy.
If your range has rentals.
