National Treasure

The following weapons were seen in the film National Treasure:

National Treasure (2004)

Jericho 941

The Jericho 941 appears many times during the film. It is first seen when Ian's (Sean Bean) henchman pulls a stainless Jericho on Ben Gates (Nicolas Cage) inside the Charlotte. It later appears suppressed during the break in at the National Archives and the chase through Philadelphia. Other Jerichos are seen in Ian's catering van.

FN Five-seven

Ian (Sean Bean) and his men use the FN Five-seven for their weapon of choice, sometimes using them suppressed.

FN Five-SeveN USG (U.S. Government)- 5.7x28mm.

Smith & Wesson 5906

Towards the end of the movie, Ian's (Sean Bean) gun has switched to a Smith & Wesson 5906.

Early Model Smith & Wesson 5906 - 9x19mm. The early model 5906 pistols had the finger step trigger guard, but they changed it to the rounded trigger guard for 'ease of production'.

I'm pretty sure one his Ian's men used a suppressed Beretta Inox, might have been a 92FS. Technically not a gun but they also used a taser on one of the guards.
