If she wants a pistol, get her pistol. However, I recommend getting her a 20 gauge or .410 shotgun. There may be other factors that prevent such a consideration.
I gave a 20 gauge saiga to my mother-in-law for home defense. I also gave one to my sister-in-law so it did not look like I don't about her. Anyway, both my sister-in-law and mother-in-law had no problems blasting away. They shot up alot of defenseless milk jugs and soda bottles.
The only complaint was that the guns were ugly. I told them to go to the gun shop and get a pretty gun if they want a pretty one. I can only afford ugly guns as gifts.
Well, they did.
Each one now has this.
the in-law's choiceAnd gave back the Saigas, which I sold for less than $100.00 loss.
My sister-in-law is also now a hunter because she shot "that dam rabbit in her garden" a few months ago.
