A decent number of C96 Mauser pistols were present in Finland's civil war, many of them coming into the country with the Finnish Jaegers, and others from a variety of sources, commercial and Russian. They were used by both the Reds and the Whites, and in both 9x19mm and 7.63x25mm. After the end of the civil war, when the military was standardizing, the C96s were handed over to the Civil Guard, where they generally remained until recalled to Army inventories in 1939. They once again saw service in the Winter War and Continuation War, and went into military stores afterwards until eventually being surplussed as obsolete.

One of the interesting aspects of Finnish C96s is that many of them come from the so-called "Scandinavian Contract" batch (for which no contract has actually turned up). These appear to be guns made in 7.63mm that were numbered as part of the early production in the Prussian "Red 9" series, probably for delivery to specific German units or partner forces during World War One.
