In a fight for your life against an Undead horde every second, and bullet, could spell life or Undeath. Reloading in the middle of battling a heavy swarm could spell disaster for you, and your survival buddies.
For those who hate the idea of needing to reload you pistol every 15 or so rounds, Calico Weapons Systems have the perfect gun for you. The Calico M-110 Pistol holds 100 rounds using it’s patented Helical Feed system, or the equivalent of 10 clips full from the Sig. It fires compact .22 bullets so there’s you can pack plenty of extra rounds, but if you’re ever in a situation against the Undead where 100 rounds is not enough, you’re pretty screwed anyway.

They also make a 9mm variation for those who feel the need for a little more kick.
