Suicide Squad is the 2016 feature film adaptation of the popular DC Comics series of the same name. The film centers around a special unit created covertly by the US government and codenamed "Task Force X", aka the "Suicide Squad", which is comprised of notorious "meta-human" criminals and assigned to take on impossible missions in exchange for reduced sentences on their crimes.

Wrist Magnums
Deadshot (Will Smith) is also armed with dual wrist weapons called "wrist magnums" that are built from Glock 19 pistols. The props used in the film were designed and custom made by Walter Klassen FX and Movie Armaments Group (this included "design work, CAD renderings, machining, assembly, finishing and powder coating"). New CNC-machined frames were created for the the Glock 19s and the magazine release and ejection of the one mounted to Smith's right wrist were reversed so that the casings would be able to eject upwards. The blank-firing wrist guns were fully automatic, fired via a thumb trigger connected to a system involving air tubes, a pneumatic actuator, and regulated CO2 canisters hidden in the holstered Glock 18s on Smith's back. According to Walter Klassen FX employee Taku Dazai, firing them created a "rooster tail of fire" and a "huge plume of fire", plus they "sound insane". They are chambered in 9x19mm, due to the fact that they can be seen loaded with the magazines from Deadshot's Glock 18s.
