Dredd is a 2012 science-fiction film that stars Karl Urban as the title character. The film is based on the comic book character "Judge Dredd", who first appeared in comic strips in the British science fiction anthology "2000 AD" and was first adapted into a 1995 feature film that starred Sylvester Stallone as Dredd. The 2012 film is a "reboot" and the cast includes Lena Headey and Olivia Thirlby.
The following weapons were used in the film Dredd:
The "Lawgiver" is the standard pistol carried by the Judges in the film, including Dredd (Karl Urban) and Cassandra Anderson (Olivia Thirlby), as well as Judges Lex (Langley Kirkwood), Chan (Karl Thanin), and Kaplan (Michele Levin). It can fire in several different modes, which are selected via voice activation, and features a digital display that keeps track of its remaining ammunition.
When being psychically interrogated by Anderson, Kay (Wood Harris) fires a Lawgiver in his imagination, but it fails to wound her. Later, when he attempts to use Anderson's own Lawgiver on her, he finds that it is coded to its owner's DNA, and will self destruct if anyone else attempts to use it.
Prop wise, the Lawgivers seen in the film appear to be Glock 17 pistols housed in futuristic shells.
The weapon's various fire modes include:
Rapid Fire (fully automatic).
Armor piercing rounds.
Incendiary rounds (these appear to be white phosphorus).
Stun (A non-lethal electric charge that incapacitates the target).
"Hot Shot" - a superheated round capable of melting flesh. In the comics, these are heat seeking rounds that track targets based on their specific heat signature. However, it is not clear whether they retain this feature in the film.
"High-Ex" (High Explosive).
Silencer Mode. The Lawgiver features a built-in suppressor that retracts into the frame when not in use.
Amos (Junior Singo), one of the kids who confront Dredd and Anderson at the information terminal carries a Vektor SP1. Many criminals also carry them.
Star Model B
Freel (Luke Tyler), one of the kids who confront Dredd and Anderson at the information terminal carries a Star Model B. Another is seen in Ma Ma's safe room at the end.
Star Model BM
What appears to be a Star Model BM is seen in Ma Ma's safe room.
Shotguns
Remington 870
One of Mama's criminals can be seen firing with what appears to be a pistol-gripped Remington 870.
Some gang members are seen with Over and Under Shotguns of unknown make. They appear to have their barrels cut down and stocks removed.
Beretta A300 (Fictional Mock-Up)
Judge Alvarez (Edwin Perry) carries a Beretta A300 fitted with fictional dressings to appear futuristic. While its appearance brings the SPAS-12 to mind, Dredd crew confirm that it is in fact a Beretta A300-series semi-automatic shotgun in a SPAS-like casing.
Submachine Guns
Heckler & Koch MP5A3
Towards the end of the film, Cassandra Anderson (Olivia Thirlby) uses a Heckler & Koch MP5A3. This particular weapon is fitted with a "Navy SEF" trigger group, which is essentially a Navy trigger housing with the non ambidextrous SEF selector and markings. Her MP5 switches between having a three-lug barrel and a "smooth" barrel (similar to that of a chopped and converted HK94) in a continuity error.
Armscor BXP
Zwirner (Jason Cope), one of the criminals in the opening chase scene, fires an Armscor BXP at Dredd. Several other thugs in the movie carry the BXP as well.
Micro Uzi
Several gang members use Micro Uzis throughout the film.
Assault Rifles
Vektor R5
Several criminals can be seen with slightly dressed up Galil Pattern rifles. As this feature was filmed in South Africa, it can be assumed that these weapons are actually Vektor R5s.
A pair unidentified machine guns can be seen mounted to the sides of the motorcycles used by the Judges. They appear to be fed by drum magazines, and bear a resemblance to the Browning M1919 series.
Fictional gatling guns can be seen on pedestal mounts. The concept designer involved confirms that they were "loosely based on the GECAL and were using .50 BMG shell casings [...] except we made ours six-barreled".
