S.W.A.T.: Firefight is a 2011 direct to DVD Sequel to the 2003 film S.W.A.T.. The film follows LAPD SWAT officer Paul Cutler (Gabriel Macht), who is assigned to train SWAT officers in the Detroit Police Department in the latest tactics. The story for this film was co-written by three former LAPD SWAT Officers.
Walter Hatch was seen holding a SIG-Sauer P229 with a nickel-plated slide. When he was disarmed, his hostage Rose (Kristanna Loken) picked it up. LAPD and SWAT officers has the standard one as their sidearm.
Alongside the Colt Law Enforcement Carbine, S.W.A.T. Officers were also seen using Heckler & Koch MP5A3s equipped with KAC railed forends and SureFire flashlight/vertical foregrip unit throughout the movie. Cutler also used one during the final shootout.
Uzi
The leader of the robbers is armed with an Uzi in the grocery store.
Shotguns
Mossberg 500
In the opening credits, a SWAT officer loads a Mossberg 500 as identified by the close up shot of the name on the gun.
Customized Ithaca 37 "Stakeout"
A customized Ithaca 37 "Stakeout", presumably the same one from Miami Vice, is used by a robber during the grocery store scene.
Remington Model 887 Nitro Mag Tactical
In the opening scene, a thug was using a sawed off Remington Model 887 Nitro Mag Tactical and SWAT officers later on use regular 887 Nitro Mag Tacticals.
This could potentially be the first film appearance of the Remington Model 887.
Rifles
Bushmaster ACR Carbine
Sgt. Paul Cutler (Gabriel Macht) uses a Bushmaster ACR Carbine as his primary. The EOTech is clearly put on backwards in several scenes.
This could potentially be the first film appearance of the ACR.
Colt Law Enforcement Carbine
Many S.W.A.T. Officers use variants of the Colt Law Enforcement Carbine throughout the movie with a variety of sights and gear attached to them. The Detroit SWAT team was later seen using training models that shoot paintballs.
Training Law Enforcement Carbine
The Detroit SWAT unit used Law Enforcement Carbines that had blue colored handguards and fired paint-balls in training.
Unknown AR-15 Carbine
It has an flat-top upper-receiver that lacks a forward-assist, a case-deflector, or an ejection-port cover.
AKMS
An AKMS is fired by another robber during the grocery store shootout.
Custom Norinco Type 56
Slater tries to defend his home from thugs using a custom Norinco Type 56 similar to the one seen in Belly.
SIG SG 551
Walter Hatch's accomplice uses an SIG SG 551 (Possibly the new A1 version) during the final shootout.
Sniper Rifles
Remington 700 PSS
A Remington 700PSS was used by SWAT officer Watters when he was tasked as sniper. He then uses it again during training.
Barrett M107
Walter Hatch (Robert Patrick) uses an Barrett M107 at a shooting range to scare Cutler. For some reason he was charging the handle for every shot. It might or might not be for dramatic effort or the blanks they used didn't cycle semi-automatically. It's also possible that they didn't have any actual blanks and used special effects for the muzzle blast.
A customized Craft Apple Works (CAW) 40mm airsoft launcher was seen in the opening scene used by a SWAT officer firing non lethal "disruptor" shells. It seemed to have a Magpul stock on it and Aimpoint sight.
