Coach Gun is the title of a group of shotguns and are manufactured exclusively by Jakobs. The Coach Gun is obtained randomly from any suitable loot source.
Usage & Description
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 two rounds consuming the first shot.
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.
This variety of Coach Gun will be incompatible with Gaige with her Smaller, Lighter, Faster skill as it would reduce the effective magazine size to zero.
This variety is used for Salvador with always active Money Shot.
