The SIG-Sauer P228 is the main sidearm of nearly all the NCIS agents in the series including Special Agents Leroy Jethro Gibbs (Mark Harmon), Anthony DiNozzo (Michael Weatherly), Timothy McGee (Sean Murray), and Ziva David (Cote de Pablo). FBI Special Agent Tobias Fornell (Joe Spano) is seen carrying a SIG-Sauer P228 in some episodes, notably "Identity Crisis" (S5E04). In a flashback to an assassination operation in Paris in Season 5's "Judgment Day parts 1 & 2", Gibbs uses a suppressed SIG-Sauer P228 to kill ex-KGB assassin turned contract killer Anatoli Zukov. In Season 5's "Lost and Found" (S5E09), Abby Sciuto (Pauley Perrette) fires a SIG-Sauer P228 into her water tank to perform a ballistics test, while a Boy Scout from McGee's troop looks on with a grin.
The Beretta 92FS (used in lieu of the Beretta M9) appears as the issued sidearm of various military personnel and in the hands of various characters throughout the series. Corporal Damon Werth (Paul Telfer) holds a stolen Beretta at Gibbs in a rehab facility in "Corporal Punishment" (S5E10).]]
The Glock 17 is another frequently-used handgun in the series. NCIS Director Jenny Shepard (Lauren Holly) takes a Glock 17 out of her desk drawer in Season 5's premiere "Bury Your Dead" (S5E01). DC-Metro Detective Andrea Sparr (Gretchen Egolf) draws a Glock 17 in Season 5's "Stakeout". In Season 5's "Lost and Found" (S5E09), Det. Collins (J.R. Bourne) aims a Glock while searching a state park for a fugitive.
In Season 5's "Judgment Day, Part 1", Mike Franks gives Jenny Shepard (Lauren Holly) a Heckler & Koch P2000 SK to use. Franks says the gun is a clean, with no registration number and is the one Jenny uses when engaging the shooters in the diner.
In Season 5's "About Face" (S5E17), Tesla Suskavcevic (James Logan) pulls a Jericho 941 on Jimmy Palmer from his car. Oddly, the gun that appears in his hand during Jimmy's flashback to their first encounter is a full-sized Desert Eagle.
In Season 5's "About Face" (S5E17), criminal Tesla Suskavcevic (James Logan) opens fire on Jimmy Palmer (Brian Dietzen) with a Desert Eagle sporting a stainless steel finish. Oddly, when Tesla is confronted at the end of the episode, his gun is a Jericho 941, or "Baby Eagle." Aside from the possibility that he owns two pistols, it is also possible that the Desert Eagle that appears in Jimmy's memory is a trick of his imagination, making the gun he saw appear much bigger than it really was. This is consistent with the theme of the episode, emphasizing how shaken Jimmy is after being shot at.
Mike Franks (Muse Watson) carries a Smith & Wesson SW1911PD with the full 5" barrel as his sidearm. It can be seen in the Season 5 episodes "Judgment Day, Part 1" and "Judgment Day, Part 2". What differentiates the PD model are the front serrations on the slide that's similar to those in such handguns as the Kimber. The pistol also has a desert tan Crimson Trace grip-mounted laser sight.
In Season 2's "Pop Life" (S2E16), club owner Ian Alfred "Bulldog" Hitch (Steven Brand) is seen using a Ruger GP100 to threaten one of his dancers, Samantha "Jade" King (Mya Harrison). In Season 4's "Cover Story", a blued Ruger is used to threaten Abby.
In Season 6's "Capitol Offense", McGee falls into a small pond where he finds a Smith & Wesson Model 10 that may have been used in a Navy lieutenant's murder. DiNozzo calls it a "Smith & Wesson. 38 Kit".
In the Season 3 episode "Deception," a security guard holds a Smith & Wesson Model 19 on Ziva and Tony, but Ziva kicks the weapon out of his hands. What appears to be a S&W 19 is used by a murder victim's brother in Season 8's "False Witness" to intimidate her murderer.
Gibbs (Mark Harmon) carries a Model 37 with a black finish in an ankle holster as his backup weapon. In the Season 3 episode "Mind Games", he uses it to threaten sadistic serial killer Kyle Boone (Christopher Shyer). In the later Season 3 episode "Probie," he gives it to McGee, whose weapon has been temporarily confiscated, to back Gibbs up as they go to question a suspect. In the Season 9 episode "Restless", it was seen beside ex-con Curtis when Gibbs and the NCIS team (except Ziva) were approaching him on the roof of a taco restaurant building.
A nickel Smith & Wesson Model 37 Airweight revolver is used to kill a bully on a Navy base in the Season 6 episode "Hide & Seek". Checking out its violent history causes Abby Sciuto (Pauley Perrette) to label it an "evil gun" and describe it as possessed (as it was used in convenience store hold-ups and other crimes each time it changed hands).
A Smith & Wesson Model 637 Airweight revolver is found on the floorboard of a car by DC police in Season 4's "Faking It" (S4E04). A 637 is also used by Ziva in Season 5's "Recoil".
A Smith & Wesson Model 66 is said to have been used by Amanda Reed (Jamie Luner) in Season 1's "Dead Man Talking" (S1E19). Gibbs referred to it as being "small, and easy to conceal." However, this is an error since the image of the gun that flashes on the lab screen (a stock product photo from the S&W catalog) is a Smith & Wesson Model 60, not the Model 66. The Model 60 is much more concealable than the larger framed Model 66. The 66 is also pulled by distraught housewife Greta Boyen (Rebecca Staab) in Season 2's "Terminal Leave". The 66 also is used by "kidnappers" in Season 8's "Defiance" (S8E15).
Ziva carries a Smith & Wesson Model 340PD as her backup gun, which she carries in an ankle holster and she once dual wielded along with her SIG in Season 6's "Dead Reckoning". She is seen briefly handling it before going undercover in Season 8's "Dead Air" and dual-wields it again with her SIG in Season 9's "Newborn King" (S9E11).
Mossad Officer Malachi Ben-Gidon (T.J. Ramini) uses an FN P90 during the firefight on the Damocles in Season 7's "Good Cop, Bad Cop". Two P90s are also visible in the "sanctuary" in Season 7's "Power Down".
In the series premiere "Yankee White" (S1E01), an Al Qaeda sleeper takes a Heckler & Koch MP5K-PDW from the armory of Air Force One. Two Heckler & Koch MP5K-PDWs can be seen in the "sanctuary" in Season 7's "Power Down".
SRT members are seen carrying Heckler & Koch MP5A2's during the hostage situation at the school in Season 3's "Bait". Russian special forces posing as pirates in Season 5's "Chimera" also carry Heckler & Koch MP5A2s with dedicated forends and Navy trigger groups.
In Season 1's "Enigma", Col. Will Ryan (Terry O'Quinn) takes an Heckler & Koch MP5A3 from one of his captors. In Season 1's "Split Decision", Gibbs goes undercover as an arms dealer, and uses a Heckler & Koch MP5A3. Several are also seen in the "sanctuary" in Season 7's "Power Down".
In Season 6's "Deliverance", a gun dealer shows an Intratec TEC-9 to a potential client, saying "TEC-9, full auto, empty a clip in 4 seconds" and encourages him to fire it, the burst hitting the roof of the abandoned warehouse and causing the body of an already-slain Marine to fall through the skylight. It was also seen in Season 3's "Iced".
A terrorist in Season 6's "Dead Reckoning" uses a Skorpion SA Vz 61 to shoot at Trent Kort before being killed by him. Kort then uses the Skorpion to shoot another terrorist. While usually chambered in .32 ACP, there is evidence that Vz61 clone pistols were chambered in .380 in the 1980's.
In the Season 2 finale "Twilight", several terrorists can be seen firing AKMS rifles at Gibbs and the team to no avail. The weapon is also used by various other characters in the series.
Imperial Japanese soldiers are seen with the Type 99 Arisaka Rifle as Ernie Yost (Charles Durning) remembers his time on Iwo Jima in Season 2's "Call of Silence" (S2E07).
Two Heckler & Koch G36Cs can be seen in the "sanctuary" in Season 7's "Power Down". A G36C with a mounted suppressor on the barrel is seen in Season 9's "Enemy on the Hill" (S9E04) when Gibbs and Tony uncover the assassin's hidden arms stash in his garage.
What appears to be a Winchester rifle converted to resemble a Henry 1860 rifle is carried by Sheriff Boyd (Lance Henriksen) and then used by Gibbs to shoot down a helicopter in Season 6's "South by Southwest" (S6E17). The rifle, which is referred to as a "Henry" by Boyd, is seen fitted with a Vernier sight and has a longer octagonal barrel of a Henry, but is side loading like a Winchester.
The M4A1 carbine can be seen used by various US Military personnel and gunmen throughout the series. In Season 5's "In The Zone" (S5E15), US Marines as well as Tony are seen carrying M4A1 during an investigation in Iraq.
