If you had to grab one fully loaded handgun and run into the night during the Zombie apocalypse what gun would you grab? You don't get to take extra ammo or anything. Just the gun itself fully loaded with whatever is attached to it. You will have to find extra ammo on the run. My choice would be my Beretta PX4 Storm (complete with Zombie bayonet). Hard to beat 18 rounds of 9mm in an easy shooting, reliable, and accurate gun. Plus, 9mm should be pretty easy to find later.
