Zombieland is a horror/comedy about four survivors of a Zombie Apocalypse who are traveling west, looking for a place where there are no Zombies. The Two girls Wichita (Emma Stone) and Little Rock (Abigail Breslin) are sisters and are going to the amusement park, Pacific Playland, where they believe is zombie free. Columbus (Jesse Eisenberg) and Tallahassee (Woody Harrelson) are not so sure. In the film, survivors usually don't share their real names for fear of getting too attached, so people are known by the city they are from. On the poster, the characters of Wichita (Emma Stone) and Little Rock (Abigail Breslin) are carrying a chainsaw and a baseball bat, however these weapons were only used in the film by Tallahassee (Woody Harrelson) before he ever met the girls: the chainsaw in flashbacks and the baseball bat in the Supermarket when he's takes on the fat zombies.

The Following guns appeared in the film Zombieland:
Armed with twin pistol-gripped Mossberg 590 Mariner shotguns, Tallahassee (Woody Harrelson) distracts the hoard of zombies in Pacific Playland while Columbus (Jesse Eisenberg) attempts to save Little Rock (Abigail Breslin) and Wichita (Emma Stone).
Mossberg 500
Wichita (Emma Stone) carries a Mossberg 500 Shotgun with rear pistol grip, forward pistolgrip and shell holder. In usual movie fashion, she fires more shots than the magazine tube of the gun can hold.
Just a thought, is it possible that this could be a Maverick 88 rather than a Mossberg 500?
They are both essentially the same weapons except the Mossberg has a top mounted safety on top of the receiver and the Maverick 88 has one mounted on the trigger guard. Taking a look at the 3rd picture, I'm not seeing a receiver mounted safety, also both of the guns are manufactured by the same company and use the same accessories. (Just a thought)
IGA Coach 12 gauge shotgun
Despite having a choice of more suitable weapons, Columbus (Jesse Eisenberg) insists on using and keeping an IGA Coach double barreled shotgun, despite it's very slow reloading time compared to the Submachine guns and pump shotguns carried by his friends.
In his endless quest to find a Hostess Twinkie and kill Zombies, Tallahassee (Woody Harrelson) carries an 6 shot Winchester 1892 "Mare's Leg" with a standard lever, not the enlarged loop of other famous versions of the gun (such as the one from Wanted: Dead or Alive ) - .44-40.
Stainless Steel M1911A1
Tallahassee (Woody Harrelson) fires akimbo with two pistols in the shootout at the amusement park. The one in his right hand is either a Stainless or Satin Nickel M1911A1 Variant - 45 acp.
Satin Nickel SIG-Sauer P228
Tallahassee (Woody Harrelson) left hand gun during the fight is a Satin Nickel SIG-Sauer P228 - 9mm. However in a continuity break, at the end of the gunfight, he has TWO nickel M1911A1 pistols.
Walther PPK
Wichita (Emma Stone) points a Walther PPK at Tallahassee (Woody Harrelson) during an early standoff when he aims his Mare's leg at Little Rock (Abigail Breslin).
Norinco Type 56
A Chinese AK (possibly a Type 84 with folding bayonet) is used by a survivor to fight zombies with little success.
Winchester 1890 Pump action rifle
Little Rock (Abigail Breslin) carries a small/medium caliber pump action rifle with exposed hammer (most likely a Winchester 1890 Pump action rifle). She uses it to shoot Zombies at the amusement park.
Glock 17
During Columbus's explanation of Rule #2, "The Double Tap", a Glock pistol (quite possibly a Glock 17 due to size) is used by an Asian businesswoman to shoot a zombie on a crowded street, but she doesn't check to see if it's dead and pokes at the body. The zombie jumps up again and bites her leg, dragging her down so that other zombies can kill her.
