Why do I like the pistol? It gives you a fast sprint speed, and that it unloads clips long enough to stall the zombies and let you reload. I can unload a clip while walking backwards and then relaod and still unload another clip. Pistal is fast. Although my 2 SMGs come first, when I need to reload on both of them, I switch out for my pistol.
Actually to survive in quarentine the guns arnt' the matter, the hiding spot it. I hid in a spot for a couple of rounds with only a pistol, and I was able to run to the safe house quickly every time and while the big crowd of people are in teh glass safe house going all crazy, I'm in the barred one just sitting around waiting for the timer to end.
