National Treasure

The following weapons were seen in the film National Treasure:

National Treasure (2004)

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.
