Do usp sd/ ump sd mags even spawn?

[Yuval 5]

i never saw them beside when found with the gun itself.

Do they even naturally spawn IG?

[Guest Biiddy]

You can find them in the ammo boxes at stary tents, the boxes at heli crashes and just in general at heli crashes i think

Checked in them and they don't spawn there.

The normal mags spawn in western ammo boxes, found in the stary-berenzino tents. there will be five of them in one box

both SD and normal mags spawn with the gun at heli crashes

We need normal ammo to work in SD weapons!

Can't, the ammo and shafting of the gun is crafted especially for that ammo type. Any other just wouldn't fire or break the firearm.
