Finnish troops captured bit under 200 machineguns of this type (most of them in 1941) during Continuation War. Also Finnish troops soon noticed the reliability problems these weapons. Aimo Lahti studied captured DS-39 machinegun and in year 1942 he planned it 8 improvements, which considerably reduced the problem. Maybe the most important improvement was decelerator switch, which was added to the weapon's bolt, as the original high rate-of-fire had proved related to reliability problems. Other improvements included making gas-piston thinner (otherwise it typically jam the weapon after only 1,000 shots or so) and adding chamber for soot in end of gas-piston (otherwise the soot could jam gas-piston after some 4,000 - 5,000 shots). Holes of gas-regulator were also increased in size to allow more gas getting to gas-piston and angle of contact piece was changed. In addition also firing pin was thinned. The last but not least of improvements was modifying the weapon's feeding system so that Finnish 200-round metal ammunition belts M/32 could be used. While these Finnish improvements reduced reliability problems of DS-39 in some extent, they failed solving the basic problem - the feeding system of this machinegun had been poorly designed and it simply didn't work well. Late 1942 Finnish military withdraw all captured DS-39 machineguns from the troops and sent them to VKT (Valtion Kivääritehdas = State Rifle Factory), where this 8-part improvement plan was implemented. After making these improvements the machineguns were re-issued to Finnish frontline troops. While not part of the improvement plan Finnish military removed the attachment of optical sight from the captured DS-39 (it seems that the optical sights belonging to these weapons were not captured - at least not in real numbers). Finnish soldiers also usually removed the weapon's shield, as the protection it offered was highly questionable. Year 1943 Finnish Army typically issued either 20 250-round fabric belts or 25 200-round steel belts with each DS-39 machinegun. In its highest the number of DS-39 in Finnish use peaked to 175 and after 2nd World War 145 of them still remained. During Continuation War Finnish frontline troops used these machineguns. After World War 2 the remaining DS-39 were warehoused until being declared obsolete year 1986 and mainly scrapped. Nowadays unknown number of Finnish-captured DS-39 machineguns remains in Finnish military museums and collections of Finnish collectors.
