Notes: "The Carl Gustaf Stads Gevarfaktori of Sweden manufactured the KP m/45 submachine gun, which is a simple but reliable weapon that has changed little since it was introduced in 1945. The weapon was manufactured as the "Port Said" by the Egyptian army and has been used in Indonesia as well. The m/45 (Model 1945) is commonly called the 'Carl Gustaf' or 'Swedish K.' In addition to the standard 9mm Luger, Sweden has developed a special high-velocity round called the 'Patron m/39' for use in the M45.
The Swedish K submachine gun is a fairly conventional submachine gun made of steel stampings. The rear sight is an 'L' type and the front a post; both have protective ears. The charging knob is on the right of the receiver and has an old-fashioned safety notch in the channel; the charging knob can be used to lock the bolt in the forward position by pushing it down. The weapon fires only in the full-auto mode, so there is no selector. The stock pivots at the rear of the pistol grip, and the magazine release is at the rear of the receiver." - Duncan Long

"The Carl-Gustaf is fabricated by standard metal-stamping methods. The metal stock can be folded forward along the right side of the weapon. Simple in design and appearance, the gun has the good material and sound construction typical of Swedish craftsmanship. Its most novel feature is an accessory barrel, for firing blanks or special close-range ammunition; this barrel has an unrifled bore of smaller diameter than the standard barrel. The blank ammunition has a plastic bullet which is pulverized as it is forced through the constricted hole in the barrel, leaving the muzzle as a harmless puff of smoke. A protector screws onto the muzzle to deflect any small particles. The special close-range target ammunition has a plastic bullet with a small steel ball cast into the nose. This ammunition is fired without the muzzle deflector; when the plastic bullet is crushed, the small steel ball continues through the barrel to give good accuracy for firing practice up to a range of 50 yards. If a live cartridge should be fired by mistake in the practice-firing barrel, the bullet sticks in the barrel without damaging the gun....While the Carl-Gustaf probably received limited use in the border skirmishes between Egypt and Israel, its first wide-scale combat use was by Egyptian fighting Israel, French, and British forces invading Egypt during the Suez Canal crisis in 1956." - Johnson & Lockhoven
