During the first season, LAPD Det. Sgt. Rick Hunter (Fred Dryer) carries a Heckler & Koch P9S with muzzle compensator, also seen during the opening credits. He sometimes refers to it as "Simon". In "The Garbage Man" (1.11), both James "Sonny" Dupree (Christopher McDonald) and his friend Ramos (Nicholas Worth) handle Hunter's H&K P9S before Dupree takes out the magazine and ejects the chambered round to hand it back to Hunter.
Walther PPK
Hunter's partner Det. Sgt. Dee Dee McCall (Stepfanie Kramer) carries a black Walther PPK during the pilot episode.
Walther PPK/S
After the pilot episode, Det. Sgt. Dee Dee McCall (Stepfanie Kramer) carries a Walther PPK/S with white grips during the first two seasons. Hunter describes it as a "police issue .38", possibly suggesting that McCall's PPK/S is chambered in .380 ACP.
Beretta Model 90
Hunter's partner, Sgt. Dee Dee McCall (Stepfanie Kramer) uses a nickel Beretta Model 90 with white grips during some first season episodes.
Colt Detective Special (1st generation)

In "Legacy" (1.05), mobster Billy Vincent (Kip Gilman) accosts McCall and kidnaps Sandy Newton with a suppressed Detective Special. In "Flight on a Dead Pigeon" (1.06), Benny (Robert Costanzo) holds his Detective Special (an S&W Model 10 Snub in the previous shot) on Hunter and McCall but McCall (Stepfanie Kramer) takes it away from him and carries it during the scene. In "High Bleacher Man" (1.09), ex-con Elton Gavin (Michael Baseleon) uses a Detective Special during a store holdup but is stopped by Hunter. McCall later finds a Detective Special inside the gym bag of mob hood Whitey McFee (Alan Autry), saying the three spent bullets inside were used to shoot at Hunter (even though the gun used in that scene was a S&W Model 19).
Colt Detective Special (3rd generation)
Several characters throughout the course of the show use third generation Colt Detective Specials. In the pilot episode, a bank robber (John Diehl), the pimp Whispering Willie (David Labiosa), and Justin Taylor are seen with Detective Specials.
Smith & Wesson Model 19
The bank guard in the pilot episode has a Smith & Wesson Model 19 holstered, taking it out after he goes with Hunter to chase down the suspects. A mobster uses one when breaking into Hunter's apartment in "Hard Contract" (1.02). Whitey McFee (Alan Autry) uses a Model 19 to shoot at Hunter from his car in "High Bleacher Man" (1.09) but, in a case of gun continuity, the gun found on him later by McCall is a Colt Detective Special. In "The Snow Queen, Pt. 2" (1.14), both the drug dealer Louie and Vic Terranova's right hand man Tony Boy (Joseph Cali) have Model 19s. Several mobsters in "The Last Kill" (1.17) have Model 19s.

In this episode, it often alternates between a Model 66 and Model 67.
Coronado Springs, Texas Sheriff Jake Cutter (Bo Svenson) carries a Smith & Wesson Model 67 in "A Long Way From L.A." (1.04). In a continuity error, this often switches between a Model 67 and a Model 66.
M1911A1
After the killing of mobster John Vincent in "Legacy" (1.05), Det. Terwilliger (James Whitmore Jr.) shows Hunter and McCall the evidence bag with the murder weapon, a M1911A1 in it, prompting Hunter to tell him to "never pointed a loaded bag" at someone. Hunter then asks how many bullets are remaining in the "clip" (meaning magazine), and Terwilliger tells him four. McCall then interjects that the "clip" (again, meaning magazine) holds eight. It's possible that this 1911 variant has an eight-round magazine loaded into it, or the episode's writers simply made a mistake. One of Deakin's henchmen in "Flight on a Dead Pigeon" (1.06) also has a 1911. Motorcycle policeman Doug Kirkwood (Marc Alaimo) keeps a 1911 in his holster, seen in "The Shooter" (1.10). Drug dealer Snazzy Louis Green (Jason Ronard) has a 1911-carrying bodyguard in "The Beach Boy" (1.15). In "Rape and Revenge, Pt. 2", McCall (Stepfanie Kramer) takes a 1911A1 from a Curaguay soldier.

Tommy Largo (Madison Mason) threatens Hunter and McCall with a suppressed Security Six snubnose in "The Last Kill" (1.17).
Single Action Army
Although he never uses it, "cowboy" bounty hunter Jimmy Joe Walker (Wings Hauser) keeps a Single Action Army in his trunk in "Dead or Alive" (1.08). A Single Action Army using .45 Colt silicone bullets, described as "cop killers" by Hunter and McCall, is the sidearm of serial killer Deke Broder (Robert Dryer, no relation to series star Fred Dryer) in "The Shooter" (1.10).
Desert Eagle
LAPD Sgt. Rick Hunter (Fred Dryer) uses a .357 Magnum Desert Eagle during some episodes of the first season, beginning with "Dead or Alive" (1.08). The Desert Eagle is explained to be a gift from his Mafia father at his graduation, causing McCall to lament that all she received was a set of encyclopedias. However, Hunter had been on the police force since at least the 1970s, making it very unlikely that he could have received a Desert Eagle, which weren't produced until 1982, at his police graduation.
Ruger Redhawk
In "High Bleacher Man" (1.09), Det. Terwilliger (James Whitmore Jr.) arms himself with a stainless Ruger Redhawk to guard Elton Gavin (Michael Baseleon), who grabs the Redhawk from Terwilliger's holster once he is no longer a witness.
Smith & Wesson Model 586
When Hunter (Fred Dryer) disguises himself as a motorcycle cop to lure out the serial killer in "The Shooter" (1.10), he wears a Smith & Wesson Model 586 in his holster that becomes a Colt Python for close shots of it firing.

NYPD Sgt. Jackie Molinas (Dennis Franz) uses a Smith & Wesson Model 13 when he questions Scully (J.D. Hall) the taxi driver in "The Snow Queen, Pt.1" (1.13). It is presumably a backup or throwaway weapon he obtained so that it wouldn't be traced back to him after killing Scully. One of the drug dealing Chinese thugs killed in the restaurant in "The Beach Boy" (1.15) has a Model 13.
Beretta 92SB
In "The Snow Queen, Pt. 2" (1.14), Sgt. Dee Dee McCall (Stepfanie Kramer) pulls out a Beretta 92SB as her personal weapon, kept in a cabinet at home.

Heckler & Koch MP5A3
One of Demarest's thugs in "High Bleacher Man" (1.09) fires at Hunter and Gavin with a Heckler & Koch MP5A3.
The lack of barrel lugs in this shot suggests that it's a HK94 Chopped and Converted to resemble the MP5.
MAC-10
A hitman named Tommy Largo (Madison Mason) uses a MAC-10 when he tries to kill Hunter and McCall in "The Last Kill" (1.17).
MAC-11

Winchester Model 70
After Hunter and McCall pick up Wally in "A Long Way From L.A." (1.04), Sheriff Cutter (Bo Svenson) shoots at them with his Winchester Model 70, which he had previously stated was the .30-06 rifle stolen by Wally for his escape. Hunter (Fred Dryer) fires a shot from it into a barrel, extracting the bullet to prove that Cutter's rifle had killed Wally.

During the Vietnam flashbacks in "Fire Man" (1.18), several U.S. soldiers are seen with M1 Carbines.
M16 (SP1) with A2 handguards
In "Sniper" (1.19), Sgt. Dennis Balzer (Jack Starrett) uses an M16 (recognizable by the slab-side lower receiver and absence of a forward assist button) with Lone Star Ordnance A2 type handguards. At the end of the episode, Hunter (Fred Dryer) also handles this weapon. It is described in dialogue as firing a .223 NATO round and is always seen fired with a twenty round magazine and a scope.
