The 12 Gauge Pump-Action Shotgun, Single Shotgun, or just Shotgun, is a single-barreled shotgun that uses 12-gauge buckshot shells. It is used by Serious Sam in most games, but also used by Cloned Shotgunners in Serious Sam 3: BFE, Serious Sam VR: The Last Hope and Serious Sam 3 VR: BFE.


The pump-action shotgun fires one shell every time the fire key is pressed. It fires seven pellets in a rectangular shape, and has to be cocked each time the weapon is fired. The shotgun remains much more accurate at range than the Double Barrel Coach Gun, thus it is a better choice for ranged shooting than the latter, with each pellet dealing ten points of damage, making a maximum total of 70 damage if all the pellets connect.

The shotgun in Serious Sam 1 has a high rate of fire, with a short delay time between shots. In Serious Sam 3, 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 magazine. Its pellet spread allows it to only hit things from point-blank to medium range.

In the Serious Sam Fusion 2017 version of Serious Sam 3, the shotgun has been improved to carry a maximum of 15 shells per magazine, with a faster reload speed and increased range overall. This makes the shotgun a much more versatile weapon.

In Serious Sam's Bogus Detour, the shotgun has a surprisingly tight spread, enabling the pellets to travel some distance. Like the shotgun in Serious Sam 3, the shotgun has to be manually reloaded, though the shells are inserted into the shotgun rather than using a clip magazine.

In Serious Sam 4, there appears to be two variations of the shotgun, a regular variant and one equipped with a grenade launcher.

Alternate fire modeEdit

Like several weapons that will be appearing in Serious Sam 4, the shotgun may have an alternate firing mode, as seen in the developer gameplay update video posted by Croteam and Devolver Digital. [1]From the footage, the shotgun can be seen equipped with an M203 grenade launcher, mounted just below the pump, as seen on the M4 ​​or M16 in real-life, though it is smaller.

Despite looking like an M203, it is unknown what it will fire. From its appearance, it will most likely fire grenades, though it may also use a special type of ammunition, such as explosive shotgun slugs.


In The First Encounter, the shotgun is first acquired in the Temple of Hatshepsut and in the first level of every era in The Second Encounter. In Serious Sam 3: BFE and Serious Sam 3 VR: BFE, the shotgun is acquired near the end of Into the Spider's Nest, but can be obtained earlier in Summer in Cairo as a secret. In Serious Sam's Bogus Detour, Sam first obtains the shotgun inside the Temple of Ptah in Knee Deep in Sand.


Serious Sam 1Edit

  • The pump shotgun works best against weak enemies, such as Bombers, Firecrackers, Kamikazes, Rocketeers, 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 a 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 3: BFEEdit

  • The shotgun's relatively fast rate of fire and somewhat-low spread makes it handy against weak enemies, such as Rocketeers or Cloned Soldiers. 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 a 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 its rate of fire is fast enough that it's possible to squeeze out a second shot quickly if one shot doesn't kill it.
  • Much like its classic counterpart, it takes two close to medium range shots to kill a Gnaar, though the player can wound it with a shot from the SOP38 Pistol and then finish it off with the shotgun for an easy kill. This also helps to conserve ammo.
  • Make sure to reload often. 10 (or 15 in the Fusion version) shots can be burned through quickly if the player isn't paying attention, it is a good idea to tactically reload.

Serious Sam's Bogus DetourEdit

  • The shotgun is one of the most effective weapons in the game, as the weapon's spread is tight enough to hit enemies at up to medium range, and it does a lot of damage per pellet fired. Its ammunition can also be found in abundance.
  • It is useful for close to medium-range elimination of weak enemies, such as Beheaded Kamikazes, Gnaars, Kleer Skeletons and Orc Troopers.
  • The weapon is also effective against Minor Bio-mechanoids, provided that the player is close to it and fast enough to dodge its lasers.

Behind the scenesEdit

  • 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, HD and VR versions, though, this has been fixed.

  • In previous games, Sam does not physically pump the gun between shots. Sam's hand does not move, though the handle does. This is fixed in Serious Sam 3.
  • The Xbox version of Serious Sam 1 has a different, slightly improved model for the pump shotgun.
  • The HD and VR (except for Serious Sam 3 VR: BFE) versions of the shotgun does not eject a shell between shots.
  • The shotgun appears to be a combination of the Remington 870 Police Magnum and a Mossberg 500 Cruiser, while the Serious Sam 3 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 Serious Sam 3 version of the shotgun holds 10 shells (15 in Fusion 2017) in its magazine, but realistically, the magazine's size is only just big enough to hold 3-4 shells.
  • The Serious Sam 3 shotgun's iron sights resemble the M1014's iron sights.
  • In Serious Sam 3, despite using 12-gauge shells, the weapon's magazine receiver sports a label for 5.56x45 NATO rounds.
  • In Serious Sam 3, despite its realistic appearance, the shotgun's pellet spread is in a fixed rectangular shape like its classic counterpart.
