Fargo - Season 1
The following weapons were used in Season 1 of Fargo:
The Glock 17 serves as the standard issue sidearm for the Duluth Police Department. It is carried by Officer Gus Grimly (Colin Hanks) and Duluth SWAT operators. FBI Special Agents Webb Pepper (Jordan Peele) and Bill Budge (Keegan-Michael Key) also carry Glocks as their sidearms.
Beretta 92FS Inox
Lorne Malvo (Billy Bob Thornton) draws a Beretta 92FS Inox and places it on his car seat in anticipation of an ambush. However, when he is rammed by Wrench and Numbers the gun falls out of his reach, forcing him to use a knife to defend himself instead.
Taurus PT911 Stainless
SIG-Sauer P226 Nickel
Lester Nygaard (Martin Freeman) arms himself with a nickel SIG-Sauer P226 with pearl grips to protect himself from Lorne Malvo (Billy Bob Thornton). Interestingly, the nickel P226 was the weapon-of-choice for the kidnappers in the original movie.
Colt Official Police
Smith & Wesson Model 13
Smith & Wesson Model 66 Snub
Smith & Wesson Model 29 Nickel
12 Gauge Double Barrel Shotgun
A 12 Gauge Double Barrelled Shotgun is purchased by Lester Nygaard (Martin Freeman) prior to the events of the show. It is later used by Lorne Malvo (Billy Bob Thornton) to murder Chief Vern Thurman (Shawn Doyle)
Remington 870 Pistol Grip
A member of the Duluth Police Department is seen firing a regular Remington 870 at the house rigged by Lorne Malvo (Billy Bob Thornton). Another 870 is seen in the patrol car used by Deputy Molly Solverson (Allison Tolman).
Heckler & Koch MP5A3
Heckler & Koch UMP
Mr. Wrench (Adam Goldberg) and Mr. Numbers (Russell Harvard) both use Heckler & Koch UMP's when they ambush Lorne Malvo (Billy Bob Thornton) during the blizzard. Malvo later uses one against the Fargo organised crime syndicate.
Chazz Nygaard (Joshua Close) illegally owns a Daewoo K3 with rail forearm, heat shield, vertical grip, rail-mounted rear sight, and M4-style collapsible stock. The K3 is meant to be a stand-in for an M249 SAW, and Chazz is said to have purchased the weapon from a friend who works in the Minnesota National Guard base Camp Ripley. He stores it in a secret compartment in his gun safe. Although the weapon is said to be an M249, it is clearly recognizable as a K3 by the shape of the gas tube and front sight (the show is filmed in British Columbia, where the K3 is always used as a stand-in for the M249).
Duluth SWAT officers throw a flashbang grenade into the house rigged by Lorne Malvo to act as a distraction.
