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 Season 1's "Missing" (S1E20), Major Joe Sacco (Derek Webster) holds a Beretta as he looks for Dinozzo in the sewer.
The Glock 17 is another frequently-used handgun in the series. In "Enigma" (S1E15), FBI Special Agent Tobias Fornell (Joe Spano) is seen drawing a Glock.
A Smith & Wesson Model 66 is said to have been used by Amanda Reed (Jamie Luner) in "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.
