This is the Russian PPSh submachine gun. It's from the second world war.
Made shortly after the Kukri Machete. I wanted to see what I could achieve without following a tutorial. I didn't make a high-poly version of this weapon. I used edge wear on all of my materials to mask away these hard edges. But if you want to make your weapon look the best it can I suggest you do spend the extra time to create your high-poly and bake it down.
The main reason I gave the drum magazine a separate texture is because this way it could easily be swapped with a different kind of magazine.
