I was carrying a S&W Shield 9MM for a while. Nice concealability but low round count.
My new carry is a S&W M&P 9C 2.0. I'm really loving this gun so far.
For revolvers I carry a model 13 or 629 both in 4 inch in leather. For Semi autos I carry LC9s and Ed Brown 45 Commander. Won’t carry foreign equipment. Guns or ammo.
