Well i don't know if this topic has been ever again anywhere but i kinda found a little glitch so that you can use any weapon you like on driveby except a few others
well you can find which weapons work and which do not while in game
so first of all you just need the full aim cheat which for the pc version is: OUIQDMW ps2: up, up, square, L2, right, x, R1, down, R2, circle and i'm not sure if works on xbox but i guess it will work: Up, Up, X, LB, Right, A, RT, Down, RB, B
so all you gotta do is simple
but you need and the jetpack cheat too
There are only a few steps you gotta do so you'll be able to use this glitch/bug.
1.Choose the weapon you want to use
2.Get in a vehicle
3.Use the spawn jetpack cheat pc: YECGAA ps2: Left, Right, L1, L2, R1, R2, Up, Down, Left, Right xbox: Left, Right, L Trigger, White, R Trigger, Black, Up, Down, Left, Right
4.Press gas and as quick as your vehicle starts to moving press the button that leaves the vehicle so it will drop the jetpack
5.Now you can use any weapon you want

Enjoy
