Do any of you guys have a truck/car gun that you keep in the trunk or a gun rack? If so what is it and what is purpose for having it? I know some people like to keep a carbine for a SHTF/get home situation. My purpose would be more for a knock around gun to use on varmints and pest around the farm. Right now I'm working on putting some qaulity sights on a 243 handi rifle that I picked up for cheap. Any suggestions for me to change or improve? Thanks.
