The hostage taker, Goran Tomasic (Xhemi Agaj) in the first episode shoots a woman in the back with a Luger P08 and holds another woman at gunpoint with it before being shot by Ed Lane's sniper rifle. Goran's son Petar (Danijel Mandic) also uses a Luger in the Season 1 finale to hold Lane up before he is killed by Braddock with his Remington 700PSS.
Glock 17 second generations with tactical flashlights are the issued sidearms of the SRU team through the series. Other police officers are also frequently seen with Glock 17s as well. By the third episode "Haunting The Barn", we finally see Sgt. Parker draw his Glock. We also see Ed Lane has been outfitted with one of these Glocks. In Season 2, many of the Glocks become 3rd generation models, also outfitted with tactical lights.
Juliana's sidearm is a Glock 26. This gun was likely chosen because Amy Jo Johnson's hands were too small to hold the full sized Glock 17 so the subcompact model was selected. In "Clean Hands" (S2E03), Agent Delia Semple (Kari Matchett) shoots the foreign serial killer with her Glock 26
In episode "First in Line" (S1E02) when a man (Henry Czerny) becomes enraged that his daughter can't get a new heart, he draws a Smith & Wesson 5904 off a hospital guard and begins a standoff. He accidentally scores a non-fatal shot on an officer after less lethal is ordered to stop him when he reveals the safety is on, and then turns it off and hits an officer's vest.
In " Asking for Flowers" (S1E04), a Smith & Wesson 5946 was used by the outraged woman, Rebecca Kessfield (Chandra West). In "Custody" (S2E13), Donald Mitchell (Alan Van Sprang) uses a Smith & Wessson 5946 to take Adam Westfall (Darrin Baker) hostage. A hostage taker in "Terror" (S3E11) uses a S&W 5946 with Novak Sights. The gunman who wounds Ed Lane in the Season 4 premiere "Personal Effects" is also armed with a 5946.
A Beretta 92FS is used by the bank robber in "Who's George?" (S1E05). It is also used by the mentally-ill veteran SRU officer in "Haunting The Barn" (S1E12). A Beretta is seen in a Russian hostage taker's car during "The Fortress"(S2E02). One is seen in "Clean Hands" (S2E03), used by Walter Volcek (Peter Outerbridge), the father of a victim of a serial killer to try get revenge. It should be noted that he racks the slide at least three times throughout the episode before he shoots it.
Seen being used by Ed Lane in "Planets Aligned" (S1E09) is a CornerShot, both with and without an ACOG scope (which is rather useless on a CornerShot anyway). A Glock 17 is fitted on the end.
One of the men who takes Justin Fraser's (Ryan Kennedy) wife hostage holds a chrome plated Desert Eagle Mark XIX .50 AE to her head in "Remote Control" (S2E06).
Michael McKewon uses a Beretta 84BB "Cheetah" during the bank robbery in "Remote Control" (S2E06). It is later taken by Justin Fraser (Ryan Kennedy). In Season 2, episode 11, the kidnapper had also had a Beretta 84BB. They even ID the caliber as .380 ACP.
A Beretta 92FS Inox is used by a man who is trying to protect his brother from a gang in season 2 episode 9, "Exit Wounds". One of arms dealer Mark Watson's henchmen in "The Other Lane" (S3E05) fires a 92FS Inox at the SRU team as they enter his house. Corporate robber Jamie Dee (Brent Dier) also uses an Inox during "Run Jamie Run" (S4E03).
In Season 1 episode 3, a Taurus Judge is used by drug dealer Sean Keenan (Alex Poch-Goldin). He calls it the "Jury", and mentions it "Takes 5 rounds, shotgun, single bore." It is actually a Taurus Judge firing the very slim .410 shotgun round and can also accept .45 LC rounds.
Seen in "Attention Shoppers" (S1E06) is a Smith & Wesson Model 36 owned by a female gang member, which is taken by an innocent girl that was bullied and used against them. A Model 36 is used to hold a man hostage by Brian Bauman (Hugh Thompson) in "Business As Usual" (S2E01).
In "He Knows His Brother" (S1E07), RJ Strachan (Tyler Hynes) uses a nickel plated Smith & Wesson Schofield Model 3 revolvers that according to the dialogue was carried by his great-grand father and his grandfather.
The bullied high school student in "Perfect Storm" (S2E07) steals a Smith & Wesson Model 686 with a 3" barrel from a box under his Dad's bed before taking it to his school. In "The Other Lane" (S3E05), while talking to Watson, Roy Lane inspects what appears to be a 6" barreled Model 686.
Sgt. Gregory Parker regularly has two or more officers armed with Heckler & Koch MP5A3s with tri-rails, Navy trigger groups, and forward grips at his side. Notably used by Ed Lane and SRU in Episode 4. Jules and Braddock use MP5A3s during "Perfect Storm" (S2E07). Ed Lane is also notably seen using one in "The Fortress" (S2E02) with a Navy Trigger group, although switches to his Glock so he can carry a riot shield. It should be noted Ed gradually stops using an MP5A3 over in season 3 in favor of his Glock. In one episode the foregrip disappears in the middle of the episode only to reappear seconds later. For some reason SRU officers feel the need to grab the magazine even though they have perfectly good vertical foregrips (Actually I checked its only the one actor who does that, everyone else uses the foregrip). They also rarely feel the need to rest stock against shoulder, as they are often seen holding the stock a good 6 inches away from their body.
A Heckler & Koch UMP is also seen on a gun rack in the police station. A member of SRU Team 4 is also briefly seen with a UMP in "Follow the Leader" (S3E12).
A Micro Uzi is accidentally fired by arms dealer Nick Watson's henchman in "The Other Lane" (S3E05). Both Watson and Roy Lane later use the same weapon for the remainder of the episode, only used by Watson to shoot Lane in a concealed bulletproof vest at point-blank range while surrounded by the SRU. A Micro-Uzi is also used by Tyler Hewitt (Daniel Fathers) during a kidnapping in "Through a Glass Darkly" (S4E04).
During Season 4, episode 16, "Team Player", the SRU tries to save Parker, who is being suspended by a rope attached to a pulley, being held by a former cop.
Rifles / Carbines
Remington 700PSS
Snipers Ed Lane (Hugh Dillon), Juliana Callaghan (Amy Jo Johnson), Kevin Wordsworth (Michael Cram) and Sam Braddock (David Paetkau) use Remington 700PSS rifles chambered in .308 caliber (Despite their stock slung ammo being .300 Win Mag).
Several officers use M4A1 carbine assault rifles as standard-issue weapons. Juliana (Amy Jo Johnson) uses one in the second episode to watch over a father with a gun in the hospital. It is fitted with a red-dot sight but when she looks through it, it incorrectly has a sniper reticule instead. By episode seven, just about all the main officers have used M4A1s. The props weapons used are not the similar Canadian-made Diemaco C8 carbine, which would be more appropriate for a Canadian SWAT team to use, since Diemaco (now Colt Canada) does not sell its weapons to civilian companies (including the armorers who worked on the show). Sam also uses a M4A1 in the Season 3 episode "The Other Lane".
In season 1, episode 12, the son of the shooter in the first or pilot episode uses a Heckler & Koch G3 rifle (possibly a G3/SG1 because of the Bipod) to snipe people from city hall. Braddock can identify this rifle by simply looking at the shell casing, because the G3 and CETME variants leave stripes on the shell casings, a feature caused by the fluted chamber.
Also at the range the sniper seem to have picked would have made his scope a very bad choice, despite the zoom in the scene isn't where he is supposed to be, it's too close for the sight to see his target that clearly. He was on the roof of city hall.
Members of a white supremacist group in "Follow the Leader" (S3E03) fire AK-47 rifles (distinguished by their open sights, angular wooden stocks and smooth receivers) at the SRU officers during a raid on their hideout. A drug dealer's henchman in "The Better Man" (Season 4, Episode 5) also uses an AK-47 to pin down police during a raid.
Another of Watson's guards at the docks is armed with a short-barreled FN FAL with a RIS handguard and an Elcan sight. Since it is never fired, it is possible that the weapon is the airsoft version made by King Arms.
The 6 shot 40mm Deftech rotarary grenade launcher for Law enforcement first seen in season 1 episode 4 is used by Sam Braddock (David Paetkau), but is not fired.
The Federal M201-Z Grenade Launcher is used in Season 1, Episode 7 by Juliana. It is also seen used by Sam Braddock in "Eagle Two", Season 2, Episode 1. It is again used by Mike 'Spike' Scarlatti (Sergio Di Zio) in Season 1, Episode 11, "Backwards Day", but it was not fired.
In Season 2, Episode 3 "Clean Hands" Walter Volcek (Peter Outerbridge) holds a primed M67 hand grenade to keep Sam Braddock as a hostage. He is eventually subdued when a foam gun is used to keep the grenade in his hands and not go off.
