Double Impact is a 1991 action film that focuses on a pair of twins who are raised in separate countries and environments after their parents are killed in an ambush. Reunited in Hong Kong, the twins join forces to take down the man responsible for their parents' deaths and stealing their rightful inheritance. Jean Claude Van Damme portrays both Alex, a French-raised karate instructor fond of short-shorts and the color pink, and Chad, a low level crook raised in Hong Kong and fond of cigars and leather jackets.
The following weapons were used in the film Double Impact
Alex (Jean-Claude Van Damme) uses a Beretta 92FS during the raid on the warehouse, chambering it upside down after a dive roll into combat. He later draws his second Beretta and dual-wields them for the duration of the warehouse shootout.
Desert Eagle Mark IV
A Desert Eagle MK IV fitted with a cumbersome 1980's laser sight mounted on top is used by a Triad in the drug factory shootout. Judging by the size of the bore, it was most likely a .357 Magnum version. Being the most popular version in early '90 movies.
A Colt M1911 is used by Alex in the hotel room. Chad claims it will not work, and Alex responds by firing it in excess of ten times into a window.
Colt Model 1903/1908
An Inglis Hi-Power is taken out of the glove compartment and used by Paul in the opening shootout.
Smith & Wesson Model 27
A Smith & Wesson Model 27 revolver is pulled by a Triad to coerce Chad into going with them.

A Smith & Wesson Model 29 is used by Triad gangsters throughout, and also used by Frank alongside his M1911 during the opening shootout.

CAR-15 with M203 Grenade Launcher
An M16A1 is used by Triad soldiers during the beach hotel attack, some with Vietnam style short magazines. One is recovered and used by Chad. Distinguishable as an A1 because of it's triangular foregrip and old style pistol grip.
The smugglers during the boat shootout are armed with AK-47s.
Heckler & Koch MP5A3
Heckler & Koch MP5A3's are seen in the hands of Triad members at the drug warehouse, and are also used by Chad during the raid. It is fitted with a telescoping stock, and a slimline forearm.
