IRL it wasnt quick like on mg42 for example, but it was and its better than nothing. Mod can have 2 versions of DP - with barrel change and without barrel change. First can be given on maps with well trained and well equipped soviet soilders ( NKVD forces, Red navy, Red guard ) and second can be given on maps where soviet soilders have lack of ammo and are not well trained ( typical situation for 1941-42, Opolcheniye ). I can make the animation of barrel change.
i will do something about it. making barrel change for DP means adjusting mesh and probably adding bones ( already existing animations should not have problems with it, just like i added bayo bone for rifles ), so i can add rag with its own bone to DP mesh and use it in barrel change animation.
