Snipers Ed Lane (Hugh Dillon), Juliana Callaghan (Amy Jo Johnson), and Sam Braddock (David Paetkau) use Remington 700PSS rifles chambered in .308 caliber(Despite their stock slung ammo being .300 Win Mag) and they are fitted with scopes with false reticules.
The hostage taker 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.
Sgt. Gregory Parker regularly has two or more officers armed with H&K MP5A3s with tri-rails, Navy trigger groups, and forward grips at his side. Several other officers use them as well. Many of them appear to have Navy trigger grouping.
Juliana's sidearm at the start of Season 2 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.
Several officers use M4A1 carbine assault rifles as standard-issue weapons. Juliana 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).
When a man 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 the 3rd episode dialogue, the Taurus Judge Kennon carried is called the "Jury", street name. "Takes 5 rounds, shotgun, single bore." Exact lines.
It is actually a Taurus Judge firing the very slim .410 shotgun round and can also accept .45 LC rounds.
In the 4th episode, a Smith & Wesson 5906 with a rounded trigger guard (yes, they can have different trigger guards and be the same model) was used by the outraged woman, Rebecca Kessfield (Chandra West).
In episode 7. A boy took out an old revolver that according to dialogue was carried by his great-grand father and his grandfather. So we can assume it's an old piece. Maybe a Single Action Army or something like that.
Not an SAA, I don't see an ejector piece.
From the looks of the first picture, it looks to me like a S&W model 3 revolver.
This series takes place in Canada and the father says that it was taken ashore at Juno beach on D-day, so what did the Canadians use as a sidearm in WWII? Webley?
Seen being used by Ed Lane in episode 9 "Planets Aligned" is a CornerShot, both with an without an ACOG scope (which is rather useless on a CornerShot anyway). A Glock 17 is fitted on the end.
