I was watching the Ken Burns Vietnam documentary last night and briefly saw a weapon that I had not thought of for years. During the Tet Offensive in Saigon there was a brief shot of a man in civies shooting a submachine gun known as a "Special K". They were made in Sweden. In my contingent we had an on again/off again fellow that was never in uniform, but sometimes wore ARVN Tiger Stripe that carried one. We always suspected he was with the CIA but that was never confirmed. Anyway, this was a sweet little little gun, full auto, 9mm, with 30 rd. (I think) mags. I didn't get to handle it much,but it was light and had low recoil. My recollection was that it was full auto only, but I'm not sure of that.
