Of all my handguns my G19 is my go to gun. It is small enough to carry concealed but big enough to shoot accurately. Holds 15+1 and is ultra reliable. It also fits the hand better than most regardless of the "grip angle". They are light and very low maintainence and if ever needed can be completely stripped with nothing more for tools than a small punch.
Don't get me wrong. I love my 1911s and my Sigs. But if I had to choose one it would be my G19. Hands down!
