I carry a 938, but it isn't perfect. I tend to ride the safety on a 1911, and if you do that with a 938, you will bleed. I would not recommend a 938 or anything with a safety to a novice shooter. I know I'm preaching to the choir, but you have to ingrain the release of the safety into your technique or you will likely forget it under stress. My son has a Shield; great gun. Whatever he gets, make sure he gets an adequate holster and plenty of practice. One of the quirks of the 938 is that the magazine spring is way too heavy to load easily, and I keep findling loose rounds in the bottom of my looser fitting mag pouches, so if you get one, get a tight fitting mag pouch.
I do not shoot the 938 nearly as well as I do larger guns, so I carry with extended magazines.
