FROM WIKIPEDIA
The Kulsprutepistol m/45, also known as the Carl Gustaf M/45 and the Swedish K SMG, is a 9×19mm Swedish submachine gun (SMG) designed by Gunnar Johansson, adopted in 1945, and manufactured at the Carl Gustafs Stads Gevärsfaktori in Eskilstuna, Sweden. The m/45 was the standard submachine gun of the Swedish Army from 1945 to 1965. It was gradually replaced in Swedish service by updated Automatkarbin 4 battle rifles and Automatkarbin 5 assault rifles. The last official user of the m/45, the Swedish Home Guard (Hemvärnet), retired it from service in April 2007.
