Look through my comments on this comm, I’ve done a few write ups.

Going with a Glock clone is a solid recommendation. Personally, go with the Ruger RXM. But for concealed carry, you’re going to have to think through clothing options and how to conceal it. The thickness of the average handgun can make it difficult for certain body shapes and wardrobes. If concealment without the gun “printing” is a priority, you can go with the “micro 9” category, they’ve figured out how to slim down a 9mm while keeping good capacity. These guns are typically 1" wide or less and popular models are Glock 43x, Sig P365, Canik Mc9, and the Smith & Wesson Shield Plus (that’s one of my carry guns). 2 big problems with these guns though. They often have smaller grips so they require more training and practice, and because they’re lighter weight they tend to recoil more which makes them all the more difficult to shoot. This is especially applicable for a new shooter.

Folks at dedicated gun stores will help you sort a lot of this stuff out in person. And if they have guns for rent, go try several options.

So in brief, if you’re getting just one for concealed carry and in case things get really bad - get a Glock clone.
