Monk - Season 8
The following weapons were seen in Season 8 of the television series Monk:
The Beretta 92FS is seen used by various characters in the series including police consultant Adrian Monk (Tony Shalhoub), Captain Stottlemeyer (Ted Levine), and Lt. Randy Disher (Jason Gray-Stanford). The Beretta is Randy's sidearm throughout the first half of the series, before he swaps to using a Glock 17 sometime prior to the seventh season.
In the series finale "Mr. Monk and the End, Part II" (S8E16), Monk also holds a Beretta on Judge Rickover (Craig T. Nelson).
"Lane & Westen"
Probably because of legal objections that came after the episode "Mr. Monk and the Very, Very Old Man," subsequent Beretta pistols which appeared in the series were given the fictional name "Lane & Westen." Even with the alternative name, they are clearly Beretta pistols, and in "Mr. Monk and the Captain's Wife," Evan Coker's handgun is explicitly referred to by Disher as a Beretta. To avoid confusion for any viewers, all "Lane & Westen" pistols will be referred to in this article by the "Beretta" name.
In the eighth season, Randy uses a third generation Glock 17 as his sidearm.
In "Mr. Monk is the Best Man" (S8E13), criminal Stephanie Briggs (Teri Polo) holds Stottlemeyer and Monk at gunpoint after recovering a pistol that she stuffed in a garment bag. When Stottlemeyer tells his girlfriend not to worry because the gun is not loaded, Stephanie responds by firing a round into the air - at which point the slide locks back, and Stottlemeyer informs Stephanie that the clip fell out into the garment bag, and she just spent the one round left in the chamber.
Smith & Wesson 3913
Stottlemeyer uses a Smith & Wesson 3913 as his sidearm for most of the series.
Smith & Wesson 6906
In "Mr. Monk's Favorite Show" (S8E01), actress Christine Rapp (Elizabeth Perkins), the actress Monk is protecting, uses a Smith & Wesson 6906 to "defend herself".
In "Mr. Monk Is Someone Else," (S8E04) while masquerading as contract killer Frank DePalma, Monk straps what looks like a Walther PPK to an ankle holster as a backup gun (and then conceals it with his pant leg), though only to fit in with the character.
