I have been considering purchasing a gun for a while or perhaps 2 or 3. I own a small piece of farmland, and I feel the need to be ready to defend myself if need be. My main concerns are cost, reliability, and ease of use.

UPDATE: No experience with guns, but I intend to get some kind of training and lots of practice. I want the gun(s) for protection against humans!

What suggestions, recommendations or advice do y'all have for me on the topic?
