World War Z is the 2013 feature film drama directed by Marc Forster and starring Brad Pitt as Gerry Lane, a former UN investigator who is tasked by the US government to find the source to the plague that has affected nearly the entire population of the world and turned them into zombies. The film was based on the novel of same name written by Max Brooks, the son of actor/director Mel Brooks, and the cast includes Mireille Enos, James Badge Dale and David Morse. The Brooks novel would also inspire a 2019 videogame of the same name, that is not related to the events of this film.
The following weapons were used in the film World War Z (2013):
A Philadelphia police officer is seen with a 2nd Generation Glock 17 in a promo screenshot. A man who helps Gerry in a looted Newark grocery store (Ruari Cannon) is also seen wielding a Glock. Gerry and Dr. Fassbach (Elyes Gabel) also carry Glocks after landing at Camp Humphreys in South Korea. Segen (Daniela Kertesz) later uses a Glock at the WHO lab in Cardiff, which is given to her by one of the WHO doctors as a last resort. A 3rd Generation model is also used by Gerry while aboard the Antonov An-12.
SIG-Sauer P229
What appears to be a SIG-Sauer P229 is used by one of the men that attacks Gerry's wife inside the supermarket.
Beretta 92FS
Beretta 92FS pistols, standing in for M9s, are used by the soldiers stationed at Camp Humphreys in South Korea, including Captain Speke (James Badge Dale). A US Navy SEAL who escorts Gerry Lane (Brad Pitt) to the base is seen firing a suppressed Beretta 92FS at the zombies.
Jericho 941R
Segen uses her service Jericho 941R on the Belarus Airways plane to kill some zombies before running out of ammo. Segen's left hand was amputated, so she couldn't reload the gun.
Smith & Wesson Model 15
Tommy's father (Ernesto Cantu) carries a Smith & Wesson Model 15 when the Lanes retreat to an apartment complex in Newark, New Jersey. Tommy (Fabrizio Zacharee Guido) later uses it to save Gerry Lane (Brad Pitt) from a zombie when the Lanes escape Newark by helicopter.

Trivia
In the US, trailers approved for "Appropriate Audiences" are not allowed to show people brandishing weapons at other people in the same shot, even if the people are undead zombies. Thus, Israeli soldiers' rifles were digitally replaced with walkie-talkies for these scenes in the previews.
