REPLICA Sterling SMG (like Canadian SMG C1) No serial number. Canadian testing of the British L2A1 Sterling SMG began in 1953; Canadian production of this weapon - designated the C1 Submachine Gun - began in 1958. Similar to the Sten Gun, the C1 fired 9mm ammunition from a curved magazine, had a collapsible stock, and could be fitted with an FN C1 rifle bayonet (primarily for parades rather than intended use in combat). The C1 Submachine Gun was adopted in 1958, replacing the STEN gun in general service. It is different from the British L2 in that it made extensive use of stamped metal rather the more expensive castings used by British production SMGs. It also had a removable trigger guard (for use with gloves in Arctic operations) as a standard option and used a new 30-round magazine. A 10-round magazine was also available for crews of armoured vehicles.
