The Neostead 2000 was designed in South Africa. It is a pump action shotgun, but it has a major difference: to reload, you push the barrel away from you and then pull it back, exactly oposite to other shotguns.

The Saiga-12 exists in 3 versions:Saiga-12SSaiga-12KSaiga-12S EXP-01Main differences are length (The S12K has a foldable stock) and different clip sizes.There is also a drum magazine availale which can hold 20 rounds instead of the normal 5-10 rounds.

This listing is for the following shotguns: Remington 870 Remington M11-87 Remington M1100 Stakeout (name used in Call of Duty 7: Black Ops) They are pretty much the same, and several parts are used for all three shotguns, this is why we list all three as one model here. Differences: The M1100 can hold 4+1 rounds (four in tube, one loaded) for the civil version and 10+1 rounds for the tactical (police etc) version. Games: Battlefield 2 lists the M11-87 Battlefield Bad Company 2 names it 870 MCS for "Modular Combat Shotgun".

SPAS-12 Combat Shotgun (Franchi) The SPAS-12 has no external magazine (like the SPAS-15), the shells are placed directly in the barrel. Both shotguns (SPAS-12 and SPAS-15) have a selector where you can choose, if you want to fire in semi-automatic mode or in manual pump action mode. Semi-automatic means, you just pull the trigger and the shotgun reloads automatically. In the pump action mode, you shoot and then need to pull the handle back and forth to load a new shell. In games and movies the people mostly use pump action, but in real life, this is only used for the SPAS-12 and SPAS-15 when firing tear gas or non lethal ammunition.

Full automatic shotgun.
