The Spectre M4 is an Italian submachine gun produced by SITES (Società Italiana Tecnologie Speciali S.p.A.) and originally produced by the SITES factory in Turin, Italy starting in 1984. The Spectre is designed to provide compact, lightweight firepower at close range. Most models include a top-folding stock and built-in foregrip. The Spectre utilizes a double-action trigger with built-in decocker, which allows the user to safely carry the weapon with a chambered round and for them to immediately fire the weapon without having to spend precious seconds preparing the weapon to fire if the need arises. The Spectre is perhaps most notable for its unique magazines, which feature a four column design that allows the Spectre to hold upwards of 50 rounds of ammunition while still remaining relatively compact. Italian production of the Spectre ceased in 1997, but the weapon was produced in small numbers in Switzerland by the company Greco Sport S.A until 2001.
