Piranha 3D is a 2010 3D horror remake of the 1978 original. It is set in a small town of Lake Victoria, which, as it explodes with spring break tourism, is preyed upon by a vicious pack of prehistoric piranhas unleashed from beneath the ocean floor by a small earthquake, forcing the town Sheriff Julie Forester (Elisabeth Shue) and expert diver Novak Radzinsky (Adam Scott) to fight off the Piranhas and to save Julie's son Jake (Steven R. McQueen) as well as his two younger siblings and the creators of a porn website.
The following firearms were used in the 2010 remake film Piranha, aka Piranha 3D:
Novak Radzinsky (Adam Scott) uses a sawed off Mossberg 500 to shoot at the piranhas while riding on a jet-ski and while helping people to get to the shore.
Smith & Wesson 3000 Shotgun
Deputy Fallon (Ving Rhames) uses a Smith & Wesson 3000 Shotgun to shoot at the piranhas before running out of ammo. Other Deputies use the model as well.
Sidearms
Smith & Wesson Model
Judging by the shape and color of the butt, Deputy Fallon (Ving Rhames) carries a Smith & Wesson Model 65 holstered as a personal sidearm.
Miscellaneous
X26 Taser
An X26 Taser is used by Sheriff Julie Forester (Elisabeth Shue) to shock and make a piranha explode while trying to get swimmers into the police boat.
