The Peruvian MGP series is a family of 9 millimeter submachine guns and semi-automatic pistols which have been produced by the Peruvian Navy's SIMA CEFAR (Changed to SIMA Electronica in 1996) factory since the 1980s. MGP stands for Marina de Guerra del Peru (Navy of Peru). Although compact as submachine guns, they are somewhat bulky as pistols. MGPs are simple blowback designs firing from an open bolt. They are equipped with folding stocks which stabilize the weapon when firing at longer ranges. All versions may be fitted with a suppressor and are meant to use Uzi magazines.
