NCIS: The Video Game is a 2011 point-click detective adventure game based on the popular TV show NCIS: Naval Criminal Investigative Service. The game contains 4 different cases, written by the original writers of the series. The game was released for the PC, PS3, X360 and Nintendo 3DS platforms.
The following weapons can be seen in the video game NCIS: The Video Game:
Special Agent Jethro Gibbs and Special Agent Anthony DiNozzo use SIG-Sauer P228 pistols in the game, just like in the TV show.
SIG-Sauer P226R
In episode 1 "Jackpot", a SIG-Sauer P226R is found next to a dead casino guard named Melvin Farley.
Smith & Wesson Model 15
In episode 1 "Jackpot", the NCIS agents find a Smith & Wesson Model 15. They find out, that the revolver was used by the gun store owner against the robbers.
Smith & Wesson M&P .357 SIG
In "Jackpot", if the player takes a photo of the P226R, it changes into a Smith & Wesson M&P chambered in .357 SIG. From that point, the game refers to it as ".357 Pistol", and the P226R is never seen again.
FN Five-seveN
An FN Five-seveN with built-in compensator-style suppressor can be seen on a Splinter Cell: Conviction poster at a crime scene in the trailer. The final version has a poster of a Rainbow operative with a shield and unknown pistol.
Heckler & Koch USP40
A Heckler & Koch USP40 is used to murder two undercover Navy SEALs in episode 4 "Dubai". The game misidentifies it as ".45 Pistol". The USP45 has a slightly longer barrel and grip compared to the .40 S&W and 9x19mm variants.

An AK-47 is seen on a poster promoting a rather old video game, Rainbow Six: Lockdown. This poster was seen in the trailer only. In the final version, it was replaced with a picture of an AKM. (Maybe the developers realized that a poster of a terrorist would look odd in a U.S. Navy base.)
