Check out the guns used in other screen versions of The Punisher here Despite the fact that Thomas Jane launched a fervent campaign to reprise his role as Frank Castle in a grittier, more true-to-the-character sequel, even going so far as to create a short independent film as the character, the production studio decided to go another way in 2008, casting Ray Stevenson in Punisher: War Zone, which wasn’t exactly a sequel, though it didn’t feature an origin story for the character either. This time, Frank Castle, after killing off most of the mobsters in the city, has to do battle with a disfigured mob enforcer known as Jigsaw after he was horrible disfigured during a battle with Castle—basically the setup from Batman (1989). Even though anticipation and buzz for the movie were high before it’s release, partly because it was announced to be an R-rated feature, the movie was ultimately a disappointment that didn’t resonate with fans or critics. The Punisher: War Zone (2008) Ray Stevenson Beretta M9s
Like Jane’s version, this Frank Castle carries twin pistols, only this time, instead of 1911s, they’re a pair of Beretta 92FS Inox pistols converted to fire full auto. This might have been an attempt to update the character, as the similar M9 was the U.S. Military’s service pistol at the time. In the original comics, Frank favors the M1911A1, particularly those made by Springfield Armory.
Castle carries his twin Beretta pistols in holsters on his vest.
Heckler & Koch USP Compact Tactical
Castle uses a Heckler & Koch USP Compact Tactical pistol with a spurred hammer as a back-up for his Berettas during the first half of the movie. He keeps it in a tactical thigh holsters and the rail is fitted with a weapon light.
Castle most notably uses it during the mansion and recycling warehouse shootouts.
Smith & Wesson Model 500
Castle carries two versions of the big-bore Smith & Wesson Model 500 revolver in the film. The first is a plain Hunter version with iron sights and an extended ejector shroud which he carries in his thigh holster in place of the USP Compact Tactical about halfway through the movie.
Later, Castle carries an S&W Model 500 Performance Center version with a Knight’s Armament RIS setup, a tactical weapon light, a laser sight, and a black suppressor installed, though what good it would do on a massive revolver remains to be seen.
During the final confrontation Jigsaw (Dominic West) relieves Frank of the weapon, and empties three of the four remaining rounds into Frank’s bulletproof vest, then tosses the weapon back to him to “decide” how to use the last one.
Heckler & Koch MP5K
During the initial assault on the mob dinner at the top of the movie, Castle is seen with a pair of custom Heckler & Koch MP5K submachine guns in holsters on his back.
They have satin nickel receivers and no foregrips, giving them a skeletal appearance, and also making them true machine pistols at they cannot be held with two hands. They’ve also had top rails added and, strangely enough, seem to have M4A1 style sight sections mounted on them with no front sights.
Castle uses the guns when he falls from the ceiling on a rope to shoot those seated at the table while spinning around. Not the most tactical way to introduce the new Punisher.
When they run dry, he ditches them and never uses them again.
M4A1 Carbine with Heckler & Koch AG36 Grenade Launcher
Castle again arms up with a custom M4A1-type carbine, this time for the shootout at a hotel.
It’s outfitted with KAC Quad-rails, a C-More red dot optic sight, an Advanced Armament Corp M4-2000 suppressor, and a short-barreled AG36 grenade launcher.
According to imfdb.org, the grenade launcher is actually an airsoft prop. The rifle is referred to by the Armorer on the behind-the-scenes feature as an M4 with a short barrel. It appears to be a short-stroke piston upper of some type, but it’s almost impossible to identify the exact make and model.
Heckler & Koch SL8-4
When it comes to sniper rifles, Castle uses a Heckler & Koch SL8-4 to shoot one of the members of Maginty’s gang between the eyes, then to kneecap Maginty himself.
