Notes

OSS ordered1,000 suppressors for the M3A1 submachine gun from the High Standard Manufacturing Company in May 1944. They were to be built on barrels supplied by General Motors Guide Lamp Division. Shipments of suppressed barrels commenced in August 1944.
The barrels were to be mated to standard issue M3A1 submachine guns to create the OSS M3A1 Suppressed. In December 1944 a further 4,000 suppressed barrels were ordered from High Standard. The order was completed by September 1945 and almost all were put into store and not issued.
Most suppressed M3A1s were issued to the Far East Theatre and China.
