**Complaint**
1.The Nagant has a 5 round magazine, not a 20 round.
2.The Nagant is a bolt-action rifle, not semi-auto.
3.The SKS seems to have a slower rate of fire than the Nagant.
4.The Nagant has a MUCH louder sound than that.
5.The Semi-Auto fire is slow. You should be able to fire as fast as you can pull the trigger/press the mouse button.
6.The textures on the SKS and Nagant seem to be pictures. They don't fit with the model and they don't fit ingame.
**End Complaint**
Hate to be so mean but I own a Nagant. It seems that you lacked any information in the readme for it as well. I also own an SKS.
The PPsh 41 seems correct.
