A recent thread about a long gun for a truck gun, by gunman41mag , raised some questions in my mind about what people think they may need a "truck gun" for and what characteristics may be required to meet those needs. These characteristics could vary widely based on the mission people envision for their chosen truck gun. It may not even end up being a rifle or a long gun at all. For example: someone working ranch land that covers hundreds of acres in Texas may find that a bolt gun or lever action in a rifle caliber will handle rural ranch needs of dispatching animals, killing predators, and providing some portable security. While someone living in urban area may be looking for something to get them back home through an area of urban chaos, such as Missouri or LA riots. Maybe there is no perfect truck gun, but are there categories of truck gun missions? What guns fit those different missions, semi-auto, lever gun, shotgun, pistol caliber carbine, etc.? What kind of capacity, power, feed system is appropriate or deemed necessary for the percieved mission and why? (I had a hard time in my mind seeing a scenario in my area where I would need 180 rnds of 7.62x39 preloaded in mags on hand in my truck for defensive purposes, but I live in a semi-rural area surrounded by hippies, whale saviors, and other granola eaters.) Long guns may not be practical at all for immediate threats due to limited mobility in a vehicle, so they may not be a great choice as defense against carjacking. Laws in some states don't allow a long gun to actually have ammunition in the firearm while it is in a vehicle. Some employers don't allow firearms on their property, (this includes many military installations, nuclear facilities, etc.). How do people deal with logistics? Is a pistol with multiple 15+ round mags a better option? Many argue that leaving a gun in a vehicle at all is a bad idea due to possible theft while you are away from the vehicle. Aside from possibly helping arm criminals, how much of a budget are folks comfortable with for possibly losing a firearm to theft? Just some areas I'd like to hear more about from folks here.
