Spectre M4

The Spectre M4 is an Italian submachine gun that was produced by the SITES factory in Turin. It was designed by Roberto Teppa and Claudio Gritti in the mid-1980s. Production in Italy ceased in the year 1997, with the closure of SITES, but proceeded in very small numbers in Switzerland through Greco Sport S.A., a company founded by Gritti, until 2001. The Spectre is a compact and light weapon, designed for instant firepower in close combat at short ranges. The four models have top-folding buttstocks, and were available with or without a forward handgrip ahead of the magazine housing. The largely steel Spectre has a polymer overmolded grip, magazine release and safety/selector levers.

The Spectre is used by the Swiss armed forces and by Italian special forces, and has been exported elsewhere.
