and personal defense, I would throw the gun...
Seriously though, my wife is just starting to carry something with her on 'outings'. It has taken me 'decades' to convince her to do so...
Although she has a D/S .38, she still won't carry that just to go to the mall, but will take it on longer trips.
So now she has started taking the NAA .22LR...it's better than nothing and she is now forming a habit...something a little bigger for EDC is just down the road...I can wait!
As far as...What Load?...I don't think it makes a difference with that pistol. If fact, bird shot, it the face of an attacker might do just as well.
For my wife, she has plain old .22LR Stinger...and it would!
