As you know I carry a 0.32 revolver for SD.
Now I am planning to get a handgun for my wife to carry for SD, since he drives and goes out oftenly.
The plan was shelved for few years since she was not ready to take responsibility of a gun, since kids are around. But it took a lot of time to convince her about it.
I feel handgun is the best for self defense/ home defense, in case you live in a metro in apartment and are not privileged with farm house

First of all we have decisions to make 1- Revolver or Pistol. 2 - 0.22 cal, 0.25 cal or 0.32 cal. 3- Interestingly - 0.32 IOF Anmol (since she wears salwar kurta, it is easy to conceal.
I am inclined towards 0.32 rev, so that ammo can be pooled, however recoil factor, stopping power and her ease of use is prime importance.
She is not very strong built, thus has to cautious.
I am also thinking of getting her try my rev so that an idea can be drawn on recoil.
Guys, let me know, help me with your experience.
She also like 7.62x25 tokarev on you tube
