Mitch Leary (John Malkovich) builds a plastic Composite Pistol with two barrels as an assassination weapon to kill the President of the United States. While it is questionable how well the composite material would withstand the high pressure gases from firing, it is used several times in the film without ever breaking. When at the hotel where the President is staying, Leary assembles the weapon under the party table (after practicing assembling it blind folded several times) and had previously hidden the ammunition in a rabbit's foot keychain, and the springs in a pen. The weapon appears to use .32 Smith & Wesson Long ammunition.
When the DC Metropolitan Police attempted to arrest the assassin, the DC ERT officers were armed with Uzi submachine guns with stock extended. Unfortunately, it turned out that the assassin scrambled the trace and lead the Secret Service and the police to a completely different address.The IMI Uzi is also seen when the secret service agents are rushing the president out of the hotel after the assassination attempt (the agents by the kitchen door have them).
