In Season 1 (adapted from the first Reacher novel "Killing Floor"), Reacher travels to Margrave, Georgia, and finds himself arrested for a murder that he didn't commit and is possibly part of a larger conspiracy. The entire 8 episode first season was released on the Amazon Prime streaming service on February 4, 2022.
The following weapons were used in Season 1 of the series Reacher:
In "Spoonful" (S1E03), Officer Roscoe Conklin (Willa Fitzgerald) takes a chrome Desert Eagle Mark XIX from a gun case and gives the pistol to Reacher upon his request for a gun. Reacher then uses the pistol as his sidearm for much of the season. The pistol is also seen in the hands of Mayor Teale (Bruce McGill) in the Season 1 finale "Pie" (S1E08).
Glock 17s are used by multiple gunmen, notably by a gunman threatening Reacher in "First Dance" (S1E02) (Reacher specifically refers to the pistol as a "Glock 17" in a later scene), along with hitmen in "Spoonful" (S1E03) and "In a Tree" (S1E04). Reacher himself makes use of a Glock 17 in "Pie" (S1E08).
A gunman uses a suppressed M1911-style pistol to commit a murder in "Welcome to Margrave" (S1E01). Reacher describes the ammunition fired from this pistol as "nine-millimeter, 95 grain". As M1911 pistols chambered in 9x19mm do exist, this is not impossible. Another M1911-style pistol is used by "KJ" Kliner (Chris Webster) in the Season 1 finale "Pie" (S1E08).
The Smith & Wesson 5946 appears to be the standard sidearm of the Margrave Police Department. Officer Roscoe Conklin (Willa Fitzgerald) is also seen using the pistol in "First Dance" (S1E02). Reacher (Alan Ritchson) also handles Roscoe's pistol during the same episode.
What appears to be a stainless finish SIG-Sauer P232 is given to Charlene Hubble (Kristin Kreuk) by Special Agent Picard (Martin Roach) for protection in "In a Tree" (S1E04).
What appears to be a Smith & Wesson Model 60 revolver with wooden grips is used by a gunman in "Reacher Said Nothing" (S1E07). Chief Detective Oscar Finlay (Malcolm Goodwin) uses one to shoot out tires later in the episode, although beforehand he refers to it as a ".32 snub nose".
Reacher is seen with an M4A1 carbine during a flashback to his time as a military policeman in Iraq in "In a Tree" (S1E04). "KJ" Kliner (Chris Webster) uses an M4 whil searching for Reacher in the Season 1 finale "Pie" (S1E08).
