This mod will decrease ammo and magazine size and offer other options, like no suppressors and decreased support weapons.

My reasoning was generally the following: smallest magazine size from that weapon class. 3 reloads for handguns, shotguns and sniper rifles, 2 reloads for SMGs and Assault Rifles. 1 reload for Machine Guns. If the game had default values smaller than this, I kept them to all the grades of the guns.

Note: I want to make this mod balanced and appealing, so please, leave a feedback about possible changes to future versions.

In general:
Pistols: 7 / 21
Some non-lethal pistols: 7/14 (this is actually default)
Revolvers: 6/12
Shotguns and all sniper rifles: 5/15
Assault Rifles and SMGs: 20/40
Machine Guns: 50/50
Missiles and grenade launchers: 1/6 (treated them similar to the first grade grenades)

The versions of this mod are:

Basic Versions: Two basic versions, one is the basic version and the other is the basic version without suppressors.

All the other versions include:
- Enhanced Quiet: Increased penetration of Quiet's rifles "Wicked Butterfly" and "Guilty Butterfly" allowing her to kill or tranq enemies wearing helmets or Heavy Armor with a single shot.

- Enhanced OSP:
- All the DEFAULT (Soviet, PF and XOF) Enemies' weapons (Pistols, SMGs, Shotguns, Assault Rifles and Sniper Rifles) can have suppressors equiped to them.
- All of the enemies' weapons will have piercing ammunition and the highest damage of their classes.
- The suppressors on weapons procured on site will always be unbreakable in all versions of this mod except the Basic Versions and the No suppressor versions.
- Steal an enemy's weapon using the CQC Steal and the weapon will have a suppressor attached to it. Otherwise, you (or Quiet) will have to find suppressors in the field and attach to them.

- No suppressors: I removed the suppressing properties of the suppressors. They'll no longer suppress the sound of your shots. I removed them from all weapons, don't bother trying to put them back, they'll still appear on the weapon but won't work.

- Enhanced Suppressors: This option will increase the durability of all suppressors to 250 shots. Thanks to Ryles1 for determining that this is the highest durability available.

- Unbreakable Suppressors: All suppressors will become unbreakable.

- Alternative Scope Magnifications: This option will alter most of your scope magnifications to (2-8x), (2-6-12x), (2-8-12x)
or (Extra 8X - adding an 8x step to all the scopes). The SHORT SCOPE
will be (2-6x) in all these options.

- Choking Enemies Will Put them to SLEEP.

- Support Weapons Addon: Choose from half, 2x, 5x or unlimited support weapons. This option can be installed on its own and it will work.
