In "Forced Entry" (S2E09), Laura Rowens (Megan Ward) uses a Beretta 85F to shoot a man she thought was going to attack her. In "Conspiracy Theory" (S2E19), Catherine Reynolds (Brigid Brannagh) is seen holding the Beretta on her partner in crime.
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. In the Season 2 premiere "See No Evil" (S2E01), kidnapper Kyle Grayson (William Mapother) holds one on his hostage while in a standoff with NCIS agents.
In "Vanished" (S02E03) Marine helicopter pilot Captain Todd Newell (Rob Boltin) carries a M1911A1 while hiding out in the Virginia forest and stalking his brother's murderer. In "Call of Silence" (S2E07), Iwo Jima veteran Ernie Yost (Charles Durning) brings his M1911A1 to NCIS headquarters to turn himself in for possibly murdering a fellow Marine during the war. In Season 2's "Dark Water", private investigator Monroe Cooper (Mike Starr) is caught faking the murder of an accident victim, using a M1911A1 from the home of the primary "suspect."
The Glock 17 is another frequently-used handgun in the series. In Season 1's "Enigma", FBI Special Agent Tobias Fornell (Joe Spano) is seen drawing a Glock. In Season 2's "Terminal Leave," Navy Lt. Commander Michaela "Micki" Shields (Mary Page Keller) keeps a Glock in her home.
In "Witness" (S2E14), a Glock 17L was found in the convertible sofa bed used by Petty officer Keith Dylan/Robert J. Thorn. It was misidentified as a SIG-Sauer and can be clearly seen in multiple other scenes as a Glock, most clearly when being test-fired into a bullet capture chamber by Abby Sciuto (Pauley Perrette).
In "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 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).
In Season 2's finale "Twilight" (S2E26), Gibbs (Mark Harmon) uses a police Remington 870 to flush out the terrorists in the warehouse. Kate (Sasha Alexander) uses it during the shootout before running out of ammo and tossing it to take a bullet for Gibbs.
