Good work Artyom! Nice mod!
I see the CZ 83 is a 9x18mm pistol. But here ( https://en.wikipedia.org/wiki/CZ-83
) it says that the CZ 82 is a 32. ACP gun, and the CZ 83 is just a civilian version of the 82. Did they change the caliber from the military version to the civilian? Or is it an error of yours?
The PPSh-41 has a magazine of 35 rounds, which is the standard one. But, being a nostalgic pampered teen, I remember from allo those WWII first person shooters made between 2000 and 2005 the version with the 71 round magazine. Could you add both version? Standard and round magazine? Like you did for the Tec-22.
The Bizon in your mod shoots the 9x19mm, but that's not the original bizon, it's the Bizon 2-01. The first version shoots the 9x18 Makarov (which is also already in-game). Another version you might be interested in is the 2-07, which shoots the 7.62x25 (this caliber as well already in game), but it might be redundant having 3 different versions of the same gun shooting 3 different calibers.
