Mannix is a detective TV show created by Richard Levinson and William Link, and produced by Bruce Geller (who also created the espionage series Mission: Impossible). It ran from 1967 to 1975 on the channel CBS alongside M:I.
Mannix followed the life of Los Angeles private investigator Joseph "Joe" Mannix, played by Mike Connors, and his African-American secretary, Peggy Fair (played by Gail Fisher). Mannix is of Armenian descent (like Connors himself), and is proficient in most athletics, including being a black belt in Karate, a decent skier, and an excellent pool player. He is also a veteran of the Korean War. In Season 1, he works for detective firm Intertect. Starting in Season 2, he lives and works in his own office at 17 Paseo Verde, West LA. He carries a Walther PP in Season 1, which can be seen in the intro, but starts to carry a Colt Detective Special from Season 2 onwards.
The show won the "Golden Globe Award for Best Television Series – Drama" in 1971, which was late Season 4 and early Season 5. Mike Connors himself also won an award for his portrayal of Mannix, the 1969 Golden Globe Awards (for which he was nominated six consecutive times) and 4 straight Emmy nominations from 1970 to 1973. Mannix, the series itself, was twice nominated for the Emmy Award for Best Dramatic Series. In 1972, writer Mann Rubin won an Edgar Award from the Mystery Writers of America for the episode "A Step in Time" (S5E03).
The following weapons were used in Season 5 of the television series Mannix:
The Walther PPK is a common gun used by criminals no matter where Mannix goes.
Bersa Thunder .380
While in the parking garage shootout, a Bersa Thunder 380 stands in for Ralph's PPK.
Beretta M1934
In a continuity error, Harry Nelson's (James Daris) dropped PPK turns into a Beretta M1934 when Mannix picks it up. ("Wine From These Grapes" [S5E04])
Colt M1911A1
In "Woman in the Shadows" (S5E04) , Viktor Gruniev (Eric Braeden) holds a Colt M1911A1 on Mannix to make sure the latter isn't doing anything suspicious. A little bit of trivia: By "Woman in the Shadows", he was called his stage name Eric Braeden instead of his birth name Hans Gudegast.
Revolvers
Colt Detective Special
Mannix's standard sidearm is a Colt Detective Special. It is also common gun for "goons" to carry and use.
S&W Safety Hammerless
Leslie Fielding (Rosemary Forsyth) is given a nickel Smith & Wesson Safety Hammerless as a gift by her husband Glen, and it is used to shoot a intruder in "Dark So Early, Dark So Long" (S5E01). It is also handled by the police ballistics expert later in the episode.
S&W Model 10
The Model 10 is often seen in the holsters of or being used by local sheriffs and police officers across the country.
Colt Official Police
The Colt Official Police is seen with a hodgepodge of different characters, from a young boy to a hypnotist. Most of the time, however, it is seen unfired.
Unknown Revolver
A robber in "Days Beyond Recall" (S5E06) uses an unknown revolver while shooting at Mannix. It's simply too dark to make a positive ID.
Shotguns
Unknown Shotgun
Sheriff Cisco Madeiras (Perry Lopez) uses an unknown shotgun to quiet down some workers in "Wine From These Grapes" (S5E04). The scene is too dark to confirm any certain ID but it may possibly be a Winchester Model 1912.
Rifles
Sporterized K98
One of the goons during the car chase in "Cold Trail" (S5E02) uses a custom sporterized K98k with double triggers, a custom stock, a custom barrel, and a butterknife bolt. He fires it at Mannix's left rear tire repeatedly.
Explosives
Dynamite
The Jailhouse Assailant uses what is referred to as several sticks of "dynamite" to try and kill Juan Esparza in the jail.
Various Gun Racks
Different gun racks can be seen throughout the series, often full with rifles and shotguns.
Police Wall of Guns
Wall of guns seen in the ballistics lab. Some guns such as the Mauser 1934 and the Colt M1911A1 can be seen.
