In another thread, the question was asked "what is a truck gun?". I am not sure I have ever seen a definition of the niche that would be occupied by a truck gun, and thought I would open this as a topic for discussion. I will start by describing what I use a truck gun for, and some of the things I think a truck gun should do. Here would be me thoughts on what a "truck gun" is: 1. A weapon primarily stored in a vehicle for use in wooded/rural areas. 2. My primary use is to dispatch vermin, such as poisonous snakes, varmints, and other pests. 3. It is not primarily designed for self defense against humans, nor is it a hunting weapon. 4. Range for me would be relatively short. 5. Short enough that it could stored easily out of sight in the vehicle. 6. Short and light enough that walking through the woods with it isn't a concern. 7. Needs to function with minimal maintenance. 8. Cheap enough that its not the end of the world if it takes wear from use, or in worse case scenario, stolen. 9. Rugged enough that it can take some abuse and still function. 10. When used, most of the time it would be offhand and unrested. 11. It is not a weapon you would ever pick for a specific mission, but is more of a jack of all trades, master of none. It is a compromise weapon. 12. Generally it would be used when you are on some outdoor activity, for example, riding fence rows, or cruising timber, and an unexpected need arises Presently, my truck gun is a Ruger Vaquero in 45 Colt, with the first 2 rounds being CCI shotshells, and the rest being a run of the mill 250g lead round nose. I think it does what I need it to do. What are others thoughts on a what a truck gun is, and what it should be able to do.
