The 12 Gauge Pump-Action Shotgun is a single-barreled, pump-action shotgun featured in the Serious Sam series.

Serious Sam 1 Edit


The shotgun first appears in Serious Sam: The First Encounter, Serious Sam: The Second Encounter, and Serious Sam HD. The pump shotgun fires seven pellets in a rectangular shape and uses one shell per shot.

Despite it being a pump-action shotgun, it has a high rate of fire, with a short delay time between shots. This weapon is first found in the Temple of Hatshepsut in The First Encounter and in the first level of every era in The Second Encounter.

Retail and HDEdit

Serious Sam 3: BFEEdit


In Serious Sam 3: BFE, the pump-action shotgun functions almost identically to its previous incarnations, with the exception that this shotgun must be reloaded after it has expended its ten round magazine. Its pellet spread allows it to only hit things from point-blank, to medium ranged. It remains much more accurate at range than the Double Barrel Coach Gun, so it is a better choice for ranged shooting than the former. It is as powerful as previous incarnations, each pellet deals ten points of damage, making a maximum total of 70 damage if all pellets connect.

NETRICSA informationEdit

"A single-barreled 12 Gauge pump action shotgun. Standard issue military equipment. Ordinary slug pellets are efficient for short and middle range elimination of smaller enemies. Pump-action mechanism guarantees excellent durability and high reliability. Albeit at the expense of low fire rate. Standard 10 shell cartridge allows for faster reloading and faster overall average rate of fire."

Serious Sam 1Edit

  • The pump shotgun works best against weak enemies, such as Rocketeers, Firecrackers, Bombers, Kamikazes, and male Gnaars. It usually takes one shot to down the beheaded enemies at up to medium range and one shot to kill a male Gnaar at close range.
  • The pump shotgun is also effective against single Kleer Skeletons. Approximately two shots at close range will be sufficient. However, this makes it ineffective against large hordes, due to the impossibility to kill each in a single shot (with the exception of the Serious Damage power-up in The Second Encounter).
    • The pump shotgun can also be used to finish off the latter enemy or female Gnaar that has been significantly damaged by the Double Barrel Coach Gun. This helps to preserve shells, especially early in the game, when shells can be somewhat limited depending on the difficulty.
  • The pump shotgun can also be used against small amounts of Scythian Witch-Harpies at close or medium range. The shell spread is tight enough to hit them at medium range and its rate of fire is quick enough to engage them at close range.
  • The pump shotgun is notably ineffective on enemies stronger than a Kleer. Even wounded stronger enemies will absorb more than a few shots if the player intends to finish them off.

Serious Sam 3Edit

  • The shotgun's relatively fast rate of fire and somewhat-low spread makes it handy against weak enemies, such as the Beheaded Rocketeer or the Cloned Rifleman. Even groups of them can be cleared out quickly thanks to its good rate of fire.
  • It is usually too weak to use against anything more powerful than the Kleer Skeleton unless the player is forced to use it, such as in the boss fights against the Adult Arachnoid and Major Bio-mechanoid or the Sirian Werebull miniboss. However even after that, with proper cover, it can (and without secrets, must) be used to fight against single Adult Arachnoids in early levels.
  • This is an excellent weapon to use against Aurigan Cave Demons. Their health is low enough that one or two shots will easily kill it, the spread is low enough that it can hit a Cave Demon at medium or close range with ease, and it's rate of fire is fast enough that it's possible to squeeze out a second shot quickly if one shot doesn't kill it.
  • Make sure to reload often. 10 shots can be burned through quickly if the player isn't paying attention, it is a good idea to tactically reload.
  • Despite its realistic appearance, the shotgun's pellet spread is in a fixed rectangular shape like its classic counterpart.

Behind the scenesEdit

Serious Sam 1Edit

  • In Test 1, the pump shotgun has a different firing sound compared to the one heard in the final game.
  • Also in Test 1, the shotgun's pump was placed correctly. However, in the final version, the pump was replaced incorrectly. In the Xbox and HD versions, though, this has been fixed.

Up Close and Personal

Up close and personal

Gib 20 enemies from close range with a shotgun. Doesn't matter if done with the pump-action shotgun or coach gun, but best done with the pump-action shotgun against small enemies, such as Rocketeers and Soldiers.



  • Unlike the shotgun from Serious Sam 3: BFE, Sam does not physically pump the gun between shots. Sam's hand does not move, though the handle does. This applies to all appearances of the shotgun.

Serious Sam 1Edit

  • The Xbox version of Serious Sam 1 has a different, slightly improved model for the pump shotgun.
  • The HD version of the shotgun does not eject a shell between shots.

Serious Sam 3: BFEEdit

  • The shotgun is modeled after the Remington 870MCS Tactical, however, much like the Chinese Hawk 97-2 shotgun, it is magazine-fed instead of tube-fed.
  • The magazine holds 10 shells in the game, but realistically, the magazine's size is only just big enough to hold 3-4 shells.
  • The shotgun's iron sights resemble the M1014's iron sights.
  • Despite being a 12 Gauge gun, the weapon's magazine receiver sports a label for 5.56x45 NATO rounds.
