Infinite Ammo

[Lestat]

Is there a way I can put infinite ammo on regular weapons (not custom) like spray can, camera and Fire Extinguisher?

This page says If I give 9999 ammo to a custom weapon it will be infinite:

"By default, a custom weapon has 9999 ammo (which means infinite ammo)."

https://wiki.multitheftauto.com/wiki/SetWeaponAmmo

But what about regular weapons? I give 9999 ammo to Fire Extinguisher and its not infinite. also If I give a bigger number, even if its not shown, its not infinite (For example I give 11000, it won't show but if you keep using the weapon, eventually it will hit less then 9999 and start showing).

How do I make these 3 weapons have infinite ammo? Thank you.

Simple, when the player runs out of ammo, you can give him more.
