Pistol ammo dupe

Hello, I'm using StackSizeController version 4.1.2 and I'm able to dupe ammo of a pistol by stacking 2 pistols, unstacking them again and unload ammo of one the pistols and repeat this over and over again.
Is there a way to prevent this from happening?

pistol dupe

When I unload the plugin I don't have this dupe (I can't stack the pistols when unloaded)

 

hi, can u try to del another plugins and reload this stacks, then one more try to unload ammo?

This problem is solved by reducing the magnification of weapons by 1x and setting the rest to 1000x among the category magnification lol
