The Pump-action Shotgun is one of four Shotguns available in Red Dead Redemption. Its six rounds give it the largest ammunition capacity of any of the in-game shotguns, but at the expense of slower reloads.
The player can also obtain it by killing Edgar Ross in the Stranger Side-mission "Remember my Family" outside the duel (He may have the semi-auto shotgun instead so be careful)
The player receives it simply by saving Torquemada from a zombie invasion.
The Pump-action Shotgun is unlocked into the player's regular inventory upon reaching rank 11.
The "Pump Action Killer" weapon challenges are unlocked at the same level. Completion of these challenges turns the weapon golden for the player.
Tips & Tricks
Like almost every other weapon in the game, combining Dead Eye with this shotgun drastically increases its range. It should be noted that the shot still spreads, meaning aiming for the head in Dead Eye of a target very far away will not guarantee an instant kill.
This weapon is very effective in Multiplayer. It has largest magazine of all shotguns found in the game, and it does have a stable fire rate (not too quick or slow), that prevents the player shooting the entire magazine into one enemy.
It's also quite powerful, as it can perform one-shot kill at close ranges (about 5ft) and two shot kill at up to about 15ft, though it loses out to the Semi-auto Shotgun in terms of sheer power. The Pump-action Shotgun can be more powerful than its Semi-auto Shotgun counterpart when within the one shot kill zone.
It is useful for clearing gang hideouts and other close quarter combat scenarios.
In promotional pre-release material the Shotgun appeared to be a hybrid between the Winchester Model 11 and 1897, but once the game came out, the in game shotgun was clearly an 1897.
In game the barrel and magazine tube appear to be rusted.
This is the last weapon to be unlocked in the single player campaign.
