It's unknown exactly what model of Mossberg 590 was actually used in the movie, however, Mossberg had a 590A1 model which was Parkerized (a dull, flat grayish finish), a bead sight, and a heat-shield, which the photos show, and marketed to military or law enforcement. The 590A1 would also have featured a metal trigger-guard (vs. a polymer version), and the receiver stamped "590A1". which the photos cannot depict. As available models change over the years, a model configured exactly as in the movie is currently not offered.
Heat is the 1995 crime drama directed by Michael Mann and marked the first onscreen pairing of legendary actors Al Pacino and Robert De Niro. Pacino stars in the film as Vincent Hanna, a relentless lieutenant in the LAPD's Robbery Homicide Division who is determined to take down a high end robbery crew led by master thief Neil McCauley (De Niro). Notable for its detailed depiction of the techniques used by both law enforcement and criminal elements, as well as exceptional and accurate gun handling, the film was first made as the 1989 television movie L.A. Takedown. Heat also was reported to have been viewed repeatedly by the "High Incident Bandits" robbery duo involved in the infamous North Hollywood shootout (as depicted in the film 44 Minutes: The North Hollywood Shootout).
Lieutenant Vincent Hanna (Al Pacino) carries an ivory-gripped Colt M1991A1 Series 80 Colt Officers ACP with a full-sized trigger and ring hammer as his sidearm in the film. Hanna carries his pistol on his waist in a crossdraw holster. Hanna's choice of sidearm might also be a nod to his service with the Marine Corps.
Heckler & Koch USP
Neil McCauley (Robert De Niro) uses a Heckler & Koch USP as his sidearm in the early scenes of the film. It is first seen during the armored car robbery, when he carries it in a holster on his tactical vest (along with five spare magazines). Note the checkered back of the grip and the shape of the external thumb safety and slide release, all uncommon to a SIG-Sauer P220. It is usually not seen clearly during the film, but the shape of the slide can easily be discerned during the shootout at the drive-in (when McCauley fires the gun through the window of his sedan at the shooter with the Steyr TMP). Neil then dumps his USP for the SIG-Sauer P220, most likely to get rid of the evidence, since it was used during the drive-in theater shootout.
NOTE: IMFDB previously identified this USP as the .45 ACP model. This is likely inaccurate, because the USP-45 was not around at the time that the movie was filmed (it was introduced in May 1995, nearly two years after the USP-9 and USP-40, while Heat was filmed mostly during 1994). The USP in the movie is most likely a 9x19mm model, since most pistols in Hollywood's prop houses were chambered in this caliber at the time. Further evidence of the pistol's caliber can be seen during the armored car robbery; the magazines visible on McCauley's tactical vest lack the extended floorplate that is common on USP-45 magazines, suggesting that they are actually 9mm magazines.
SIG-Sauer P220
After dumping his H&K USP after the drive-in theater shootout, Neil McCauley (Robert De Niro) replaces his USP with a SIG-Sauer P220 in .45 ACP as his sidearm for the rest of the movie. In the script it is also mentioned that he holds a .45 caliber pistol.
Star Megastar
Waingro (Kevin Gage), the unstable newcomer to Neil McCauley's (Robert De Niro) crew, carries a blued Star Megastar during the armored car robbery. He uses this one to first pistol-whip and then execute the first guard (stuntman Rick Avery) by shooting him in the face at point-blank range. He also carries a nickel one when he answers the door at his hotel suite.
Beretta 85FS
Chris Shiherlis (Val Kilmer) is seen with a compact pistol in a holster next to him when McCauley walks in and sees him sleeping on the floor. He wakes up and then sticks the holstered gun in his pants. The closest gun it seems to resemble is a blued Beretta 85FS "Cheetah" compact pistol.
Beretta 92FS
The LAPD patrol officers responding to the bank robbery return fire on Neil McCauley (Robert De Niro) and his crew with their standard issue Beretta 92FSs.
Beretta 92SB-C
Sergeant Drucker (Mykelti Williamson) carries a Beretta 92SB-C as his sidearm, which is only drawn while he is pursuing Cheritto after running out of ammunition for his Mossberg 500 shotgun.
M1911A1
One of the SWAT officers checking Shiherlis' car has an unknown M1911A1 pistol in his holster. Since Kimbers weren't issued yet to LAPD officers, it is doubtful it is a Kimber Custom II, the current sidearm of LAPD special weapons and tactical units.
Ruger KP90
Michael Cheritto (Tom Sizemore) has a Ruger KP90 in a crossdraw holster on his tac vest during the armored car robbery. This is NOT the P90, as sometimes claimed, but the stainless KP90.
Glock 19
After McCauley executes Waingro, he leaves the room, and a detective working surveillance at the hotel draws a Glock 19 on him.
Taurus PT92AFS
A nickel Taurus PT92AFS can be seen in the holster of the bank guard that McCauley kicks to the floor during the start of the bank robbery.
Revolvers
Smith & Wesson Model 36
When Hanna and his men visit Alan Marciano (Hank Azaria) in Las Vegas to question him about his relationship with Charlene Shiherlis (Ashley Judd), Det. Casals (Wes Studi) is seen in the background holding a nickel Smith & Wesson Model 36 snub nose revolver.
Smith & Wesson Model 38 "Bodyguard"
During the armored car robbery, as soon as Waingro uses his Star Megastar to execute the first guard, McCauley guns down the second guard (Thomas Rosales Jr.) as he tries to grab a Smith & Wesson Model 38 "Bodyguard" from his ankle holster.
Submachine Guns & Machine Pistols
Heckler & Koch MP5A3
Heckler & Koch MP5A3s are seen held by an LAPD SWAT officer in a hiding position during the stakeout scene at the precious metals repository. It is also used by a surveillance team watching for Shiherlis and is used by the SWAT team that is sent to the hotel in the climax.
Steyr TMP
The assassin sent to the drive-in theater (Max Daniels) to kill McCauley brings a Steyr TMP.
Shotguns
Benelli M3 Super 90
After the assassin is gunned down at the drive-in-theater, the truck driver starts to drive towards the exit, but just as he reaches the gate, Cheritto steps out from behind cover and opens fire with a Benelli M3 Super 90 12 gauge shotgun. The shotgun is a both pump-action and semi-automatic but Cheritto uses pump-action only.
Mossberg 590
Detective Casals (Wes Studi) brings a Mossberg 590 to breach the door of Hugh Benny's (Henry Rollins) apartment. Sergeant Drucker (Mykelti Williamson) carries the exact same Mossberg 590 during the firefight outside the bank after the heist. Vincent Hanna later takes one from an officer towards the end of the film as he chases down McCauley on the tarmac.
Mossberg 500
Some of the LAPD officers are seen armed with Mossberg 500s during the bank robbery shootout.
Ithaca 37 "Stakeout"
An Ithaca 37 "Stakeout" short-barreled shotgun can be seen resting behind a security desk when McCauley goes to kill Waingro in the hotel.
Remington 870
Some of the LAPD officers are seen armed with Remington 870s during the bank robbery shootout.
Rifles & Carbines
Colt Model 654
During the armored car robbery, McCauley carries a Colt Model 654 carbine, a 14.5" barreled predecessor to the M4, with M16A1-style lightweight barrel and sights. He uses his to execute the second guard (the one who tries to draw the Smith & Wesson Model 38 Bodyguard in his ankle holster), who gets hit in his right arm, his shoulder and in his chest. Based on configuration it may be a 654 upper on a GAU-5A receiver (or possibly even an SP1 receiver with a drop-in autosear to allow it fire fully-automatic).
Colt Model 733
During the armored car robbery, Chris Shiherlis (Val Kilmer) uses a Colt Model 733 short-barreled carbine as his weapon of choice. During the bank robbery, Shiherlis and McCauley both carry the Model 733. These are compact versions of the M16 rifle family with 11.5-inch barrels.
Trivia: Allegedly, footage of Shiherlis expertly reloading his rifle during the bank robbery shootout has been shown to American Special Forces trainees, with the message from their instructor, "This is how I want you to reload."
FN FNC-80
Lt. Vincent Hanna (Al Pacino) pulls out an FN FNC-80 assault rifle during the shootout on Flower Street, and uses it to kill Cheritto when Cheritto - who is firing at Drucker and several other cops - grabs a little girl as a human shield. According to the on-set armorer, Hanna's rifle was a Select Fire FNC-80 assault rifle that was chopped down by the armorer to a Para length barrel, and an M16 style birdcage was attached. The FNC-80 was imported into the U.S. as a full automatic weapon and as a Semiautomatic Sporter rifle named the FNC 223 Sporter. Despite being a full auto weapon, Michael Mann instructed Al Pacino to fire only in semi-automatic mode, because Hanna and all of the other cops who were involved in the shootout would be concerned about the possibility of endangering bystanders.
FN FAL 50.61
During the armored car robbery, Michael Cheritto (Tom Sizemore) uses a 20" barreled FN FAL 50.61 Paratrooper version with a side-folding stock. He uses his to execute the third guard with a double tap to the sternum and a third shot to the head. This is a military tactic known as a Failure Drill or Mozambique Drill, and is a prominent feature in Michael Mann's movies (it appears twice in Heat - this incident, and then at the end, when McCauley executes Waingro in his hotel room).
Heckler & Koch HK91A2
Chris Shiherlis (Val Kilmer) covers McCauley (Robert De Niro) at the drive-in theater with a Heckler & Koch HK91A2 fitted with a bipod, and manages to take out the Steyr TMP-wielding assassin with a shot to the back. Shiherlis can be seen holding the HK91A2 on the film's poster.
IMI Galil ARM
Michael Cheritto (Tom Sizemore) uses an IMI Galil ARM Model 372 with a wooden handguard during the bank robbery and the shootout. While inside the bank, the stock is removed from the mounting bracket. However, it appears when he enters the car, an obvious continuity error. He gets separated from the rest of the crew during the gun battle but managed to wound one of Hanna's men, Detective Schwartz (Jerry Trimble) by shooting him in the shoulder by a transit bus. Oddly enough, Mann refers to the weapon as a 7.62mm in his audio commentary.
M16A1 (with M16A2 handguards)
Several M16A1 assault rifles are featured prominently in the film, fitted with M16A2-style handguards and Rapidex type rear sight adjustment knobs. They are wielded by various L.A.P.D. officers, including Detective Casals (Wes Studi), Detective Mike Bosko (Ted Levine) and Detective Schwartz (Jerry Trimble). Casals uses one to assist in disabling the Lincoln Town Car being used as a getaway vehicle, and also manages to shoot and wound Shiherlis during the shootout. According to the on set armorer, the director wanted the actors to fire in semi-automatic mode only. The reason given was that the police would be less interested in 'suppressing fire' and more interested in controlled shots given the proximity of so many innocent bystanders.
A police sniper of the surveillance team watches over McCauley with a Heckler & Koch SR9(T) sniper rifle. This same sniper is seen during the stakeout for Shiherlis with the rifle.
Trivia
It appears that some of the shots composed for the film were inspired by several paintings.
