When UAC is enabled, you can add a weapon data file into your server to make sure that players who connect aren't using a custom version.
The function GetWeaponData is used to return values of different weapon stats, like damage, range, ammo in the clip, reload time, etc.
To find values that can be returned (or set with SetWeaponData), there should be a set of constants on the wiki pertaining to each one.
I'm not at my PC but if I remember right, the syntax of the function is:
GetWeaponData( int WeaponID , int DataType )
