Well, I personally am a huge fan of the .22 LR. Always have been. For those who live in the country, on farms and ranches, it is a handy little varmint gun, light on the belt, mild report, usable in places other weapons aren't, like barns and silos when loaded with light rounds like CB caps. So, for those reasons it's the gun that I most frequently have handy. It's the gun I would most likely still have on my belt during a quick run to town or on the weekend. If you know you are going into battle, my rule is if it doesn't start with a "4", it's too small. (an opinion many don't share, and I really don't want to engage in caliber bashing, I just said I like .22's...enough of that all over the internet). But, for the unexpected, the truth is, I'm probably going to have a .22.
