Nicknamed the 'Record Player' by the Soviet army, the DP was a cheap and reliable machine gun that started out in 1928. It quickly gained a reputation for being able to withstand sand and mud, and still come out able to fire off more than 500 rounds. The DP did have its share of drawbacks however. The bipod was weak and was unable to handle the abuse of firing the large 7.62mm rounds. Another problem came from the distinctive pan-style magazine on top. Capable of only holding 47 rounds, the DP was less effective at sustained fire than its belt-fed counterparts, since re-loading each magazine took so long. The DP saw Soviet front line service from 1928 to 1960, with approximately 795,000 made, including many sub-variants and licensed remakes.
DT ( Дегтярёва Танковый - Degtyareva Tankovi') modification of DP machine gun entered service in the Red Army in 1929 and became standard maching gun for all Soviet tanks. The development of this modification was carried out by G.S. Shpagin taking into account the characteristics of the installation of a machine gun in close fighting compartment of the tank and other armoured vehicles. Instead of wooden stock retractable metal one was installed. Standard bulky magazine with single in-line cartridges arrangement was replaced by the magazine with three-row arrangemeg which accomodated 63 cartridges. In 1944 back-action spring was modified and this version was designated as the DTM.
