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 one of the designers of the Spectre, Claudio Gritti, until 2001. The Spectre is used by the Swiss
armed forces and by Italian special forces
, and has been exported elsewhere.
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 polymer Spectre has a stamped-steel receiver.
The Spectre is a standard blowback firearm operating from a closed bolt; however it has some unusual features. The barrel shroud completely hides the barrel. The bolt is designed to pump air through the barrel shroud to provide additional cooling. The Spectre is hammer-fired and the trigger group is double action
with a decocker. This allows the shooter to safely carry a round in the chamber and fire immediately as the double action trigger eliminates the need for cocking prior to shooting. A manual safety is provided. Unconventional 50-round capacity, four-column magazines are provided with the Spectre, but it can also use conventional magazines.
