Women who carry, which single stack 9mm and holster would you recommend to my wife who is 5'3 115 lbs?

My wife wants to start carrying ASAP after a couple incidents with homeless at her job. If I could I'd have her shoot a few options and figure out which works best for her. Unfortunately, babies can't wear ear pro in the womb, so we need to wait on that part. I'll be doing a lot of dry fire practice with her to make the most of the situation. My concern is getting something that is either too heavy or unconformable and stays at home, or getting something that is too snappy since we can't practice with live ammo until after October. If she had a DGU, it would likely be against one person at very close range. I'm thinking a good trigger upgrade, big dot sights, magguts, and a DPM recoil spring for whatever we get. Considering a shield, G43, or P365. These all seem about the same on paper but would love some input from real world experience. Thanks! via /r/CCW https://ift.tt/2TXt9h8
