The Closer is a television crime series that currently airs on the TNT Cable Network. It stars Kyra Sedgwick as an expert interrogator who solves cases as the head of the Major Crimes Division of the Los Angeles Police Department.
The following weapons were used in the television series The Closer:
Deputy Chief Brenda Lee Johnson (Kyra Sedgwick) and Detective Irene Daniels (Gina Ravera) both carry the Glock 26 as their sidearms.
Glock 19
Lt. Tao (Michael Paul Chan) carries the Glock 19 as his duty weapon. The Glock 19 is also carried by FBI Special Agent Fritz Howard (Jon Tenney).
Beretta 92FS
Lt. Louie Provenza (G.W. Bailey) and Sgt. David Gabriel (Corey Reynolds) carry the LAPD's previously standard issue Beretta 92FS as their onduty sidearms. Detective Sanchez (Raymond Cruz) also carries a Beretta, a non-gun version of which he is seen using to shoot a mob hitman several times in the chest after he had killed an FBI agent and shot up the squad room with Lt. Provenza's weapon. He's also seen drawing it in Season 4's "Time Bomb".
In episode Serving the King, Part 2 (2.14) and L.A.P.D. SIS detective is seen with what appears to be a Wilson Customized Remington 870 shotgun. The Remington 870 is taken the place of the classic Ithaca 37 in the L.A.P.D.
Submachinegun
Heckler & Koch MP5A3
An L.A.P.D. SIS detective is seen with a Heckler & Koch MP5A3 with dedicated forend weaponlight in the episode Serving the King Pt. 2 (2.14)
Uzi
In the episode Next of Kin (3.14) two armored car robbers are equipped with Uzi Submachine Guns.
Rifles
M4A1
In Season 4's "Time Bomb", the Major Crimes Division engages in a shootout at a shopping mall against a heavily armed and armored teenage spree killer who is carrying an M4A1 carbine assault rifle. This gun is used to wound Detective Sanchez.
Remington 700
In the episode Next of Kin (3.14) Detective Sanchez (Raymond Cruz) is on a rooftop during a stakeout. He is armed with what appears to be a Remington 700PSS/700P. But with a green synthetic stock instead of the black stock. The Closer is filmed with the close technical cooperation of the L.A.P.D. so I'm assumming that the rifle is correct. A sniper (Conrade Gamble) being hunted by the squad can be seen with a Remington in the episode Show Yourself (1.4) as well.
