if u want 2 actual bullets and tracers> Open the weapon file (weapons/mp/beretta_mp etc..) with notepad++
1) Change shotCount\1\ to shotCount\2\
2) Change impactType\bullet_small\ to impactType\shotgun\
3) Change weaponClass\pistol\ to weaponClass\spread\
If u want to further script 2nd bullet spawn use .gsc
