Reacher is a 2022 Amazon Prime streaming series based on the Jack Reacher novels written by Lee Child. Alan Ritchson stars as Reacher, a former US Army investigator traveling through Georgia who finds himself arrested for a murder that he didn't commit and is possibly part of a larger conspiracy. Adapted from the first Reacher novel "Killing Floor", the entire first season was released on the Amazon Prime streaming service in February of 2022. Reacher had previously been adapted as a feature film series starring Tom Cruise as the title character.
The following weapons were used in Season 1 of the series Reacher:
A Glock 17 pistol is used by a gunman threatening Reacher in "First Dance" (S1E02). Reacher specifically refers to the pistol as a "Glock 17" in a later scene. 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.
In "Spoonful" (S1E03), Officer Roscoe Conklin (Willa Fitzgerald) is seen taking what appears to be a chromed Desert Eagle Mark XIX from a gun case and giving the pistol to Reacher. The pistol is also seen in the hands of Mayor Teale (Bruce McGill) in the Season 1 finale "Pie" (S1E08).
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.
