Coach Guns are double-barreled shotguns that have high damage and pellet count at the cost of using two rounds of ammunition per shot, coupled with a low magazine size. The typical magazine size is two, making most Coach Guns single-fire weapons; although there is an exception of three-rounded magazines, with the first shot consuming two rounds.
Among other uses, Coach Guns are an excellent choice for Anarchy-based Mechromancers: the frequent empty-magazine reloading provides quick gains in Anarchy stacks, the Smaller, Lighter, Faster skill dramatically increases the shots-per-second of the weapon, and the accuracy penalty from accumulated Anarchy stacks will have less noticeable effect on the already-inaccurate Coach Gun.

Though there is some variety in magazine size, only one variant of the Coach Gun has a magazine size under two. The common-rarity Handy Coach Gun has a magazine size of one and outputs the full 13 pellets. However, it will still use the full two rounds of ammunition on firing, pulling the second round from ammo reserve.
