Changes

**Just before RP-46 was manufactured, further experiment of DP-28 known as DPM-36 conducted with several improvement and replacement. The DPM-36 doesn't equipped with a standard Pan Magazine, where it replaced by box magazine and Maxim belt-fed system. Also, the Paratrooper version had a bayonet lug attached and shorter barrel.<ref>[https://www.forgottenweapons.com/soviet-experimental-dpm-36-lmg-variations/ DPM-38 variations of Forgotten Weapons]</ref>

*The experimental Hopper-Fed System for the DP-28 had been conducted after Japanese Invasion of Manchuria and Soviet-Japan Border Skirmish. Using the feeding mechanism as Japanese Type 11 Machinegun does, DP-28 replaced the cumbersome standard pan magazine with detachable hopper where the operator able to refill even the hopper was still attached with 5-stripper clips. However, the hopper mechanism is vulnerable of dust and dirt entrance. This so called Kubynov Hopper-Fed DP-28.<ref>[https://www.forgottenweapons.com/kubynov-hopper-fed-dp28/ Kubynov DP-28 on Forgotten Weapons]</ref>
