In reality, what we use are rifles, revolvers or pistols.
A gun is aboard a Navy vessel, that long gray thing sticking out of a turret. It uses black powder and the biggest bullets I have ever seen.
Just kidding about that, but it is true.
Other than that my weapons are just tools that I use. I get upset with them from time to time but things always seem to work out. I try to treat them as well as I can so that they will continue to serve me when needed.
