Dawn of the Dead (2004)
The following weapons were used in the film 2004 remake of Dawn Of The Dead:
In the beginning of the film when the zombie outbreak first starts, one of Ana's (Sarah Polley) neighbors can be seen with a M1911A1 pistol and threatening her to stay back before he is hit by an out of control ambulance.
Beretta 92FS Inox
Andre (Mekhi Phifer) uses a Beretta 92FS Inox as his weapon. This pistol is also used by other characters, mainly CJ (Michael Kelly) when he clears out the lower level of the mall of any zombies. Kenneth (Ving Rhames) also gets a hold of this weapon when he disarms CJ and holds it on him during the argument on the rooftop of the mall. Steve (Ty Burrell) can also been seen with a Beretta 92FS Inox with blued components (trigger, hammer, safety, disassembly latch, and slide release) when he gets out of the crashed bus, a continuity error is seen when the referred parts are stainless when he checks the gun's load.
Heckler & Koch USP
When Kenneth (Ving Rhames), CJ (Michael Kelly), Terry (Kevin Zegers), and Michael (Jake Weber) enter Andy's (Bruce Bohne) gun store to rescue Nicole (Lindy Booth), they find an unloaded Heckler & Koch USP laying on the bloody floor. This is presumed to be the gun Andy was using to fend off zombies while letting Chips, outfitted with food, through a doggy door before being bitten and infected by a zombie.
When the survivors are loading up at the gun store, a SIG-Sauer P229 pistol is seen being taken off the counter.
While the survivors are loading up at the gun store, a Beretta 92FS is among one of the weapons to be taken.
After the survivors load up at the gun store, several Glock 21s are seen afterwards. CJ (Michael Kelly) hands a pair to a wounded Tucker (Boyd Banks) to fight off the zombies chasing them in the sewers while they make their way back to the mall, CJ also uses one of these pistols as his back up weapon, and uses it to to explode a propane tank and sacrifice himself at the docks so that the zombies can't reach the remaining survivors, and the last G21 we see is the one Michael (Jake Weber) uses to commit suicide after we learn he was bitten and infected while the other survivors sail away on Steve's (Ty Burrell) boat.
Smith & Wesson Model 27
One of the mall's security guards, CJ (Michael Kelly) is seen with a Smith & Wesson Model 27 .357 Magnum when we first see him. Later in the film, a struggle ensues between the survivors that are currently in the mall and the former security guards on whether or not to let more survivors into the mall with CJ threatening to kill everyone to stay alive, but when he is distracted, the survivors disarm both CJ and Bart (Michael Barry). The revolver is then mainly used by Michael (Jake Weber) for the rest of the film.
Smith & Wesson Model 13
Terry (Kevin Zegers) uses a Smith & Wesson Model 13 throughout the film. Bart (Michael Barry) can also be seen with a Smith & Wesson Model 13 revolver before it is taken from him by the other survivors.
Smith & Wesson Model 66
Norma (Jayne Eastwood) uses a stainless Smith & Wesson Model 66 Snub Nose. Later when Norma dies, Ana (Sarah Polley) uses this weapon to kill a zombified baby, and it is also seen when the survivors go to rescue Nicole (Lindy Booth) at Andy's (Bruce Bohne).
Smith & Wesson Revolver "Non Gun"
While the survivors make their escape out of Milwaukee, Ana (Sarah Polley) uses a Smith & Wesson Model 66 "Non Gun", which temporarily replaces her actual Smith & Wesson Model 66, to put a bullet into the head of a zombified Steve (Ty Burrell). This "Non gun" was used because Polley was close to Burrell when shooting this scene, and at such close range, blanks can be considered unsafe, so a "non gun" was used.
Remington 870 (Mounted Weaponlight)
Kenneth (Ving Rhames) uses a police issue Remington 870 shotgun fitted with a Surefire flashlight attachment on the foregrip as his signature weapon. He uses it for most of the film until the survivors go to rescue Nicole (Lindy Booth). He loses the weapon when it runs out of ammunition and a zombie grabs it out of his hand. The gun was also briefly used by Ana (Sarah Polley) to incapacitate the undead Ben Cozine early on in the film.
Mossberg 500 Cruiser / Remington 870 (Compact)
One of the survivors, Tucker (Boyd Banks) has a Mossberg 500 Cruiser with a pistol grip. This weapon is also used by Michael (Jake Weber) and CJ (Michael Kelly). Tucker's shotgun switched brands several times during the movie, changing from a Mossberg 500 Cruiser to a short Remington 870 as the close up below shows.
Custom Remington 870
After the survivors rescue Nicole (Lindy Booth) and load up at the gun store, Kenneth (Ving Rhames) packs a Customized Remington 870 shotgun fitted with a magazine extension tube and Mossberg-style ghost ring sights (this is possible since some parts are easily swapped between Remington 870 and Mossberg 500 series shotguns) and uses it while the remaining survivors make their escape out of Milwaukee. Kenneth most notably uses this shotgun when he blows the top half of a zombified Andy's (Bruce Bohne's) head off. Ving also knows how to use a weapon effectively, because he doesn't flinch excessively and whenever he isn't firing, he demonstrates the excellent trigger discipline of a Marine.
When the survivors load up at the Andy's (Bruce Bohne) gun store, CJ (Michael Kelly) arms himself with a Franchi PA8 with a factory folding stock and high-capacity magazine tube, and uses it while they make their escape out of Milwaukee. From the report of the gun and the look of the wounds it inflicts, it seems he is using rifled slugs.
Heckler & Koch G36
During the opening credits during one of the news broadcasts, a soldier in Istanbul can be seen firing a Heckler & Koch G36 assault rifle (fitted with a G36C-style carry handle) before being overwhelmed by zombies.
The owner of the gun store across the street, Andy (Bruce Bohne) has an M40A1 Sniper Rifle with a folding bipod which he uses to play Hollywood Squares with the other survivors stranded in the mall on the other side of the street in which Kenneth (Ving Rhames) shows Andy a celebrity's name on a dry erase board, and Andy puts a bullet in the zombie look-a-like's head. CJ (Michael Kelly) later uses Andy's rifle to explode a propane tank to clear a path to the sewers for the other survivors.
In the opening credits during one of the various news broadcasts, a soldier (played by director Zack Snyder) can be seen firing an M60E4 Machine Gun in front of the U.S. Capitol. Note the large triangular front sight.
DVD Special Feature "Andy's Terrifying Last Days Revealed"
An extra featurette on the DVD release features a 'recovered home video' of the gun store owner Andy (Bruce Bohne), and his dealing with the zombie outbreak from (mostly) inside his gun shop. In this featurette, the following firearms are seen -
Heckler & Koch MP5A2
Safari Arms .45
In some scenes, Andy (Bruce Bohne) can be seen carrying around a Safari Arms .45 with a Surefire 310R/610R flashlight attachment mounted on.
SIG-Sauer SSG 3000
In some scenes, Andy (Bruce Bohne) can be seen with what looks like a SIG-Sauer SSG 3000 although he used an M40A1 in the film, but it's quite possible that it could have been one of the many other guns in Andy's store.
