MP5K

This mod ports the SMG model from GTA LCS and fixes the proportions making it look closer to the real life weapon. It includes a custom HUD icon for the weapon that blends in really well with other default weapons from the game.

The MP5K can become a dual wielding weapon once the weapon skill reaches the Hitman level, but before that it works like it is usually supposed to with the vanilla MP5

To install the mod correctly, you need to replace or include the model and texture (mp5lng.txd/dff) inside GTA3.img using a tool. In case you have Modloader you can drop the files in a folder.

To make the mod work, and be able to dual wield the weapon, you need to modify weapons.dat, look for the Gun data section, there are three lines of codes named MP5. Once you've found them, you have to replace them with these lines
