Hey, I just wanna suggest something that I thought would be a pretty nice idea. I sadly have no idea about how the library of PZ works..

Maybe if setting Survivors Infinite Ammo, add an extra option that will automatically refill every magazine (not in gun and not for single-bullet refillable weapons) on each reload.
That way my Guard Survivors won't need to resort to filling up to 100 Bullets into a LMG (Brita's Weapons).
You should make that an optional option of course to prevent people from liking the current method to lose that.
