Overview

The DPM (Degtyaryov Pekhotny Modernizirovanny, model 1944) is the modernized wartime version of Vasily Degtyaryov's 1927 DP light machine gun, chambered in 7.62x54mmR and fed from a distinctive 47-round flat pan magazine mounted atop the receiver. The headline change was relocating the return spring out from under the overheating barrel into a tube in the trigger housing, curing the chronic spring-fatigue stoppages of the original DP. The DPM also added a pistol grip, a manual safety, and a sturdier bipod. It retained the gas-operated long-stroke piston action with flap-type bolt locking, firing from an open bolt at roughly 600 rounds per minute with an 840 m/s muzzle velocity. It served from late WWII into the 1960s, was license-built in China as the Type 53, spawned the DTM vehicle variant and the belt-fed RP-46, and equipped numerous communist and post-colonial militaries.

Notes

Distinct from the base DP-28: the DPM relocated the recoil spring from under the barrel to a tube extending into the buttstock and added a pistol grip plus a manual safety. Year sometimes cited 1943 vs 1944; 1944 used. Rifling figures are standard-cartridge values, not source-confirmed.

Background

The DPM's whole reason to exist was one nagging flaw: on the original DP the return spring sat coiled around the gas piston directly under the barrel, and sustained fire cooked it until it lost tension and the gun jammed - so the modernization moved the spring into a tube behind the bolt. It was also the first of the line to get a proper pistol grip and a manual safety, things the 1927 DP simply never had. The flat top-mounted 'record player' pan magazine survived because the rimmed 1891-vintage cartridge fed poorly from box magazines.
