Zombieland: Double Tap
Zombieland: Double Tap is the 2019 sequel to 2009's Zombieland. Set five years later the four survivors return to battle more evolved zombies, while searching for more of the living. Ruben Fleischer returns from the first film to direct the sequel, which was released on October 18, 2019.
The following weapons were used in the film Zombieland: Double Tap:
Custom AR-15 (PWS Diablo) with Spike's Tactical Havoc Launcher
Steyr AUG A3
Winchester 1892 "Mare's Leg"
Tallahassee (Woody Harrelson) still carries a 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.
During one of the Zombie fights Columbus runs out of ammo for his Mossberg and switches to a 2.5" Colt Python. Later it's heavily implied to be smelted at Babylon.
Colt Single Action Army
Rock Island Armory M1911A1
Tallahassee (Woody Harrelson) gives Little Rock (Abigail Breslin) a custom engraved Rock Island Armory M1911A1 for Christmas, claiming it once belonged to Elvis Presley and in the same scene, Tallahassee erroneously (but understandably) referred the Rock Island 1911 as a "Colt .45."
What appears to be a two-tone Ruger LC9s can be seen getting smelted at Babylon. This gun is either backup to Little Rock's Walther PPK or it's a continuity error to the PPK.
Heckler & Koch MP5K
Little Rock (Abigail Breslin) is seen using a Heckler & Koch MP5K with a 3-lug barrel throughout the film before it gets smelted into peace symbol pendants although the only parts that's steel (or metal) is the receiver.
Micro Draco AK Pistol
It appears that Nevada (Rosario Dawson) uses an Micro Draco Pistol with 10 or 15 round magazine. It starts out as Albuquerque's (Luke Wilson) personal sidearm, but it becomes Nevada's after he is infected.
Flagstaff (Thomas Middleditch) uses a Kel-Tec KSG with various add-ons. The KSG (and likely the accessories) is anachronistic due to the fact it hasn't started production until 2011, the outbreak in Zombieland took place in 2009.
Columbus (Jesse Eisenberg) uses a Mossberg 500AT instead of the double barreled shotgun throughout the film. Columbus either lost the double barrel during the 10-year skip or traded it for the Mossberg (which was a smarter route due to a higher capacity). Witchita (Emma Stone) also wields the Mossberg during a particularly chaotic fight with two zombies. Madison (Zoey Deutsch) is briefly seen holding the shotgun for Jesse before Tallahassee takes it from her and gives it to Columbus when a zombie horde attacks the group. The Mossberg is later implied to be smelted into peace symbol pendants before entering the Babylon near the end of the film.
GE M134 Minigun
Several pistols and launchers are seen. A Desert Eagle Mark XIX (possibly a Tokyo Marui Chrome GBB Replica) can be seen on a table.
