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, and Little Rock are sisters and are going to the amusement park, Pacific Playland, which they believe is zombie free. Columbus and Tallahassee 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 and Little Rock are carrying a chainsaw and a baseball bat, however these weapons were only used in the film by Tallahassee before he ever met the girls: the chainsaw in flashbacks and the baseball bat in the supermarket when he takes on the fat zombies.
The Following guns appeared in the film Zombieland:
Armed with twin pistol-gripped Mossberg 500 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 side-saddle shell holder. In usual movie fashion, she fires more shots than the magazine tube of the gun can hold.
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.
Nickel M1911A1
Tallahassee (Woody Harrelson) fires akimbo with two pistols in the shootout at the amusement park. The one in his right hand is a nickel plated M1911A1 - 45 ACP. Actually in closeups, Tallahassee is holding an MGC replica M1911A1 in bright nickel. Continuity is broken with his handguns many times in the stuff animal booth battle sequence.
During the battle Tallahassee (Woody Harrelson) has a Nickel M1911A1 in his right hand and a Nickel SIG-Sauer P226 in his left hand, but by the end of the battle, (in a continuity break) he has two M1911A1 pistols.
SIG-Sauer P226 (Nickel)
Tallahassee (Woody Harrelson) holds a Satin Nickel SIG-Sauer P226 Pistol in his left hand. Which causes confusion is that during the fight, this gun switches to an ISS Non-Gun Silver "Flashpaper" Pistol (which is shorter than the full sized P226) which made viewers believe it was a P228.
Non Guns
When firing in close proximity to the actors portraying zombies, it is obvious that Tallahassee is using Non Guns (also known as "flashpaper" guns) for safety reasons. He uses an M1911 Non gun and a SIG PISTOL non gun to fire at the rampaging zombies.
Norinco Type 84
A modified Norinco Type 84 with an underfolder "Pig Sticker" bayonet is used by a survivor to fight zombies with little success.
Glock 17 Non Gun
During Columbus's explanation of Rule #2, "The Double Tap", a Glock 17 Non Gun pistol (also referred to sometimes as a 'flashpaper gun' is used by an Asian Businesswoman to shoot a zombie on a chaotic Atlanta street. The actress is using a "flashpaper" Non gun) due to the close proximity of the stuntperson.
Taurus Model 62C Takedown Rifle
Little Rock (Abigail Breslin) carries the Taurus Model 62C takendown rifle, a modern clone of the classic Winchester 1890 Pump action rifle) but with a shorter barrel. She uses it to shoot Zombies at the amusement park.

Beretta 92FS

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).
