Daewoo K7

The Daewoo K7 was announced in 2003 as a 9 mm silenced submachine gun (with permanent suppressor) for use with the South-Korean special forces. It is based on the K1A infantry rifle, from which the receiver and telescopic buttstock was copied. It was first displayed in the United Arab Emirates in the IDEX (International Defense EXhibition and Conference) 2003 convention.
As the K7 uses a subsonic 9 mm cartridge
The suppressor reduces the gas pressure, and the already low velocity of the subsonic cartridge reduces the firing signature significantly. Also, the suppressor distorts the sound so that it is barely recognisable as a gunshot. But just as important, the suppressor contains the entire muzzle flash so that the firer's position is hard to detect, even at night. The noise caused by a K7 is 120 decibels.[cit
