Hi there,
I thought CJ uses some of his weapons in an unrealistic way, so I edited a few things in weapon.dat, and improved the weapons.
Now Colt45, Micro Uzi, Tec-9 and the Sawed-Off Shotgun are held by two hands.
I also edited the amount of rounds in each magazine, it's realistic now. (Colt45 and Silenced Colt45 have 7 rounds now for example.)
I increased the range of each weapon, tweaked damage and removed double weapons. (Don't worry, your weapons will do more damage once you reach pro level)
Installation:
Simply put default.ide and weapon.dat to your GTASA Directory/Data Folder
If you screwed something up, or you don't like the mod itself, don't worry, I've included backup in the .rar

Version two:
Thanks to a kind suggestion here, I've edited the sawed-off shotgun animation, now it looks much realistic, as it has recoil. The file is awaiting approval.
