She outta just spring for the SW500 snubby
She might just want to stick to a small 357. Lots of options for ammo. 38spl 38+p 357 etc. If its just for self defense 357 should be more than enough and its a lot easier to shoot.
This is a good Idea, thats exactly what my dad got for my mom 20 years ago and its still the only one she likes, my dad has one also, although I recently convinced him to try a simi auto .40, he wants a glock, I carry a Sig. ( in the winter). I am going to spring for the 1911 this summer..
