CJ holds his gun up a bit like bond, the power is unbelievable,
it has 1 bullet per clip, just like in the game/movie, all you need is GTA: Ultimate Editor, then open the file with it ,
REMEMBER: Files to backup:
GTA San andreasData
GTA3.IMG
WEAPON.DAT
Warning: I take NO responsibility if you dont pay attention to the 'BACKUP YOUR FILES' Warning.
Enjoy
