Carl Gustav M/45

Kulsprutepistol m/45 (Kpist m/45) also known as the Carl Gustav M/45 or the Swedish K SMG, is a 9 mm Swedish sub machine gun adopted in 1945 (hence the designation m/45) at the Carl Gustaf G-F facility in the city of Eskilstuna by Swedish weapons designer Gunnar Johnsson. The m/45 was the official sub machine gun of the Swedish Army after World War II. The m/45 was also used by U.S Special Forces in the Vietnam War, these weapons were devoid of markings. In U.S service it was known as \"K-Rifle\" or \"Swedish-K\".The m/45 was developed in 1944-45 lending and improving many design elements from earlier sub machine guns. The sheet metal stampings used in manufacturing the German MP40, the British Sten, the Soviet PPSh-41 and PPS-43 were studied in detail. A prototype version was ready for testing in 1944 and the first production version was adopted in 1945.An interesting difference between the m/45 and most modern self loading pistols and rifles is that it is carried with the bolt in a retracted position and an empty chamber. When the trigger is pulled, the bolt charges forward, pulls a cartridge from the magazine, chambers and fires it. This results in a lock time so long that the shooter actually notices the split second between the release of the sear and the discharge of the bullet.

Variants

First production: the SMG models Kpist m/45 and Kpist m/45S featured a detachable (via removable clip) magazine support. It accepted the m/37-39 50-round "coffin" magazine and the later standard 36-round box magazine. Over time, most first production m/45's were converted by permanently riveting the magazine support to the receiver. The m/45 had a dark gun metal finish.

General production: the m/45B model features a fixed magazine support, smaller holes in the barrel shroud, a strengthened bolt buffer (in the receiver-rear), and a hook securing the buffer cap in place. Early m/45B models had the same metal finish as the m/45 but most had a grey-green lacquer finish.

Ceremonial and in UN/ONU: the m/45C is an m/45B with a bayonet mount on the barrel sleeve which was used for parade and guard duties. During the Congo Crisis in the 1960s, the Swedish UN forces used the C version extensively. The standard m/45 and m/45B have no bayonet mount.

Police: The Swedish police had the m/45 as a reinforcement weapon in their organization, but it was unlike the military model equipped with a switch for fully automatic or single shot. The police model designation was m/45BE (E = enkelskott/single-shot) and BET (T = tårgas/tear gas). The BET model become later escrow to the switch so that only single shot could be fired. BE model had the same finish as the military m/45 (black oxidized), but could be painted in black if the old finish had become too worn. It also received a modified stock in mid / late 70's (m/75) with a removable upper cheekpiece that allows the operator to wear a visored riot protection helmet (Huvudskydd m/69). BET model was painted black and would only be used to fire a tear gas canister(Tårgaskastspray m/74). To be able to shoot away the canister, a special propellant cartridge (9mm lös ptr m / T) had to be used. A red sticker on the left side of the weapon reminded the operator that they could only use that kind of ammunition. It also had a high front sight and an adjustable rear sight (30, 45 and 60 meters). The m/45 BET was repaced by Heckler & Koch MZP 1 (HP 40) in the early /mid 1990s because it was considered unfashionable and new tear gas canister was difficult to come by after that it contained the hazardous substance, Freon 12.
