The Double Barrel Coach Gun is a double-barrel shotgun that appears in the Serious Sam series.

Serious Sam 1Edit

"Double your gun, double your fun!"
Sam Stone[src]


  • The coach gun fires 14 pellets and uses two shells every time the gun is fired, twice as much as the 12 Gauge Pump-Action Shotgun. The pellets are spread in a wide box-shaped pattern. However, the pellets' wide spread makes the weapon ineffective past short range.
  • Unlike the pump-action shotgun, there is a significant amount of time between shots, which greatly decreases the rate of fire.
  • The coach gun's reload animation is significantly shorter in Deathmatch mode of the classic Serious Sam titles, giving it about the same delay between shots as the pump shotgun does.
  • In The First Encounter, the first secret appearance of the coach gun is in the Temple of Hatsheput and its main appearance is at the end of the Tomb of Ramses III.

NETRISCA informationEdit

  • Weapon: Double Barrel Coach Gun
  • Ammo: 12 Gauge shells
  • ROF: two shells manual reloading
  • Barrel: 20"


Standard double-barreled 12 Gauge shotgun. Efficient for short-range elimination of medium-sized enemies, but scatters the pellets too much to be used for long-range shooting.


  • Slow due to complete manual reloading
  • Inefficient at long range


  • When using the coach gun, the player should remember that the reloading animation between shots makes them vulnerable, and should be moving or ready to move as soon as the coach gun is fired.
  • The coach gun is an excellent anti-Kleer Skeleton weapon. A point-blank shot will always kill a kleer in one hit. Short range shots have a chance to kill the latter as well, though a few pellets might fly past the kleer, especially in Serious Sam HD. In the HD version, the Kleer has a a hit-box that conforms more in line with its shape than in the original game.
  • Sirian Werebulls are less of a threat when confronted by the coach gun. Two short-range blasts can kill one, and landing all of the pellets on a werebull is can be easily accomplished due to its size and hit-box. Alternatively, one can fire a rocket or grenade at the werebull and then finish it off with the coach gun.
  • The coach gun can also kill a Scythian Witch-Harpy in one shot at close range, in cases such as a harpy closing in to perform a melee attack. However, the coach gun is only effective on small flocks of harpies, due to the reloading time between shots leaving the player vulnerable. It is not recommended to be used when encountering a swarm.




Serious Sam 3: BFEEdit

The coach gun reappears in Serious Sam 3: BFE, this time with a new firing sound and model.


The coach gun was originally marketed for both hunting and self-defense. However, with the arrival of Mental's forces, it has become a handy anti-alien weapon.

Its 12-gauge shells excel at point blank range however, bullet spread greatly limits mid to long range effectiveness.

It behaves exactly like the coach gun from Serious Sam 1; it fires both barrels at once, but the gun is automatically reloaded afterwards. Each shot fires 14 pellets whose spread forms a large, rectangular shape.

The shotgun is first obtained at Under the Iron Cloud normally, but can be obtained in Into the Spider's Nest via a secret.

NETRICSA informationEdit

"Standard civilian double-barreled 12 Gauge shotgun. Originally marketed for hunting and self-defense, it has proven to be very effective against most aliens. Efficient for short-range elimination of medium sized enemies, but scatters the pellets too much to be used for long range shooting. Break open mechanism provides very good reliability and power in a small form factor, but yields very slow rate of fire.


  • The coach gun is an excellent weapon to use against a single or small amount of Kleer Skeletons. One shot will kill a kleer if the kleer is close enough to the player when the gun is fired. The same strategy also works on Gnaars.
  • It also works well as an "emergency" weapon against certain powerful enemies, such as the Scrapjack or the Major Bio-mechanoid. Their large size allows most of the pellets to connect at medium range, which isn't possible with other enemies.
  • This weapon is effective against groups of weak enemies, such as Beheaded Rocketeers. The large amount of pellets fired per shot can kill/gib multiple enemies with one shot, which is useful for clearing out a group of weak enemies without using ammo for the M29 Infantry Assault Rifle.
  • Its large spread makes it ineffective at anything past close range. This makes it ineffective against enemies that prefer to stay at medium or long range, such as the Witch-Bride of Achriman.


Behind the scenesEdit

  • The coach gun has a different firing and reloading sound in Test 1.
