Last Action Hero is a 1993 action comedy starring Arnold Schwarzenegger as Jack Slater, an action movie hero whose movie world is invaded by a real life kid through the use of a magical ticket. Despite being directed by John McTiernan (Die Hard), the film was a disappointment at the box office. However, in keeping with the over-the-topness of Slater's world, a ridiculous amount of firearms are featured in the film.
The following weapons were used in the film Last Action Hero:
Jack Slater (Arnold Schwarzenegger) uses an IMI Desert Eagle Mark VII chambered in .50 Action Express (based on the bore diameter) throughout the film as his weapon of choice. The Mark XIX would later replace the Mark VII in using .50 AE, although there was a brief time in which the Mark VII was released in this caliber.
Extremely Short barreled Minigun
An M134 with extremely short barrels can be seen mounted on the side door of the black Toyota Previa Van for a few seconds.
Benidict (Charles Dance) uses a custom .357 Dan Wesson Revolver target pistol. It features a muzzle break compensator on the end of the barrel to dissipate recoil and improve accuracy. It also has large, hand-hugging target grips, and adjustable target sights.
M3A1 "Grease Gun"
One of the thugs in the Red Ford F-100 chasing Slater uses an M3A1 "Grease Gun" when Danny Madigan (Austin O'Brien) enters the movie (literally).
MAC-11
When Danny day dreams about Jack Slater (Arnold Schwarzenegger) as Hamlet, he is seen firing a MAC-11 briefly before it switches to a MP5K. A thug in the red Ford pickup is also seen firing a MAC-11 from the right side window. They are noted as .380 MAC-11s based on their size, but then again, Arny and this thug are pretty big dudes.
M60
Slater is seen riding a horse while carrying an M60 slung over his shoulder in Danny's daydream of the Shakespearean play Hamlet.
One of the thugs on the pickup chasing Slater is seen using an Heckler & Koch SP89 modified to resemble the MP5K. One of Benedict's thugs is also seen using an SP89 as well.
Intratec TEC-9
Some of Benedict's thugs in Slater's house are armed with TEC-9s. The man in Slater's closet is armed with a TEC-9 with a stainless barrel shroud. The rest are described in "The Funeral" section. They are noted as TEC-9s and not the full-auto TEC-DC9s because of the shroud mounted sling loop, not featured on the TEC-DC9. They were most likely converted to full-auto for the film.
Kimel AP-9
The closet assassin also holds a Kimel AP-9, a 9mm 'assault style' pistol that closely resembles the TEC-9/DC-9 series of guns.
Heckler & Koch HK33
The assassin in Slater's closet has an Heckler & Koch HK33 slung over his back.
Remington 870
One of the police officers outside Slater's second cousin Frank's house is armed with a Remington 870. A man in the back of the Ford Pickup is also armed with a Remington 870.
Beretta 92FS
Officers in the opening sequence are armed with Beretta 92FS handguns. The officer to the left outside cousin Frank's house is also armed with a Beretta 92FS.
Beretta 92FS Inox
A stainless Beretta 92FS Inox is seen in Slater's glove compartment.
Slater pulls a Smith & Wesson revolver off his person as he reveals what a walking arsenal he is in the opening scene with The Ripper.
Colt M1911A1
Slater tosses a Colt M1911A1 off of his personal portable arsenal called "himself" in the opening scene with The Ripper.
Smith & Wesson 669
Slater tosses what appears to be a Smith & Wesson 669 to the ground when facing the Ripper.
Colt Mustang Pocketlite
Slater pulls a Colt Mustang off his ankle holster in the opening scene with The Ripper.
Colt Commando
At the opening sequence, SWAT officers are seen armed with what appears to be Colt Commando rifles, one of which is fitted with an M203 grenade launcher underslung. The Ripper throws one off the roof along with its user after emptying it into the police vehicles below. The weapons' muzzles aren't seen so a definite answer isn't certain.
M16A1
A number of LAPD SWAT officers are seen with M16A1 rifles at the beginning of the film.
Heckler & Koch MP5A3
A SWAT team member in the opening scene is seen armed with an MP5A3 fitted with a Surefire dedicated fore end weaponlight. The rest is seen in "The Funeral Section".
Colt Python
A snub-nose nickel plated Colt Python is carried by one of Benedict's thugs and is taken by Whitney (Bridgette Wilson) after she kills him. Another thug knocks it from her hands to the thug who can't catch, who not surprisingly, doesn't catch it, letting it roll into the kitchen. When Slater is shot with a shotgun in the vest, he falls and picks this gun up to shoot the man back.
Winchester 1300
One of Benedict's thugs is armed with a Winchester 1300 shotgun. He's the one who almost takes the marked bills and aims the 1300 at Skeezy at the front door. A female LAPD undercover officer at Slater's station is also seen with one.
Sawed-off Stoeger Uplander
The other thug who aims the gun at Skeezy at the front door is armed with a Sawed off Stoeger Uplander shotgun. The same guy shoots Slater in the vest with this shotgun, before being blasted with the Colt Python snub-nose.
SIG-Sauer P230
Danny decides to apparently take a SIG-Sauer P230 out of the glove compartment, and uses it to hold up John Practice before he pulls it from his hands.
Vivoldi's weapon of choice is a golden engraved Walther PPK which he uses to stop Danny for the second time from holding up Practice. A similarly engraved Walther appears in the 1990 film Darkman.
Franchi SPAS-12
Although hardly seen, one of Benedict's thugs is seen carrying a Franchi SPAS-12 when they confront them at the house. The thug is then seen using a TEC-9 when he's taken out by Slater.
Several SWAT officers at the beginning are seen holding Mossberg 590 shotguns.
Benelli M1 Super 90
The SWAT officer who gets kicked by Slater is seen with a Benelli M1 Super 90 fitted with an extended magazine tube, rifle sights and modified for box magazines.
Steyr AUG
One of the SWAT officers at the beginning of the film is seen armed with a Steyr AUG.
Mk II Handgrenade/knife
Slater pulls out a Mk 2 hand grenade to threaten The Ripper but he calls his bluff and orders Jack's son to pick up the grenade. A hidden blade pops out of the grenade conveniently (because everyone has a grenade knife right?), and stabs the Ripper in the leg.
Fact: The grenade prop was composed of three basic designs. A regular dummy grenade, a grenade with a pop-out knife (noted by the obvious knife tip sticking out of the grenade in one shot), and a leg harness for the actor to wear to make it look like the knife was stuck in his leg.
Browning M1919 Machine Gun
The helicopter that fires at Slater in the elevator is armed on one side with two mocked up Browning M1919 machine guns.
Gatling Gun
The helicopter is also armed on the other side with a mocked up Gatling gun.
A scene in the film that requires its own section is the funeral scene, where an entire mob family is attending the memorial service of Leo "The Fart". Everyone in the family pulls out a gun when Slater tries to take Leo from the funeral, being aware he is loaded with a nerve gas bomb. Guns already on the page are list here again to save space.
