From my opinion, pistols need to serve a dual role purpose – just like rifles or shotguns. Whether its on your hip while walking around the yard, or in your hand while hog or deer hunting, be sure to pick a caliber that will get the job done.
5. 22 long rifle – inexpensive, light weight, takes care of small pest with little or no problems. The light recoil makes the 22 a great choice for small framed adults, teenagers learning to shoot and people who do not like the recoil of the larger calibers.
One of the big bonuses of the 22 long rifle, it can be shot out of a pistol or rifle, this makes it a dual role caliber. From a stockpiling point of view, and you intend for everyone in your group to be armed, the most inexpensive route is the 22 long rifle. When a brick of 550 rounds cost between $12 – $20, its cost effective to stockpile thousands of 22 rounds. For $200 someone could probably buy more 22 long rifle then they will shoot in a 10 years – do that with 9mm, 40S&w, 45ACP or 357Sig.
