Strayer Voigt Infinity
Springfield Armory M1911
Colt Detective Special
Colt Detective Special with a synthetic grip can be seen being used by two Hong Kong police officers while taking cover from Rick (Leslie Cheung). The Colt DS was the standard sidearm of HKPF officers in the criminal investigation units at that time the film was released, being replaced in favor of Glock 17 pistols.
Rick (Leslie Cheung) loads a Beretta 92F at a shooting range, but never used the pistol.
Heckler & Koch MP5A3
Hong Kong Special Duties Unit officers use Heckler & Koch MP5A3s during the final shootout.
Since guns are illegal in Hong Kong, Rick (Leslie Cheung) converts his pistols into airsoft pistols. Hong Kong law states airsoft guns may not be fired with a muzzle energy above two joules of kinetic energy.
Note: It is widely believed and preached by anti-airsoft and anti-gun advocates that Airsoft guns can be readily and easily converted to fire live rounds. That idea itself is both very expensive and impractical. The same can be reverse. Although it is not impossible, it is not feasible.
