Best ISO 9mm loadout in Warzone Season 1

Even though the weapons from Modern Warfare 2 are available in the new version of Warzone, they don’t see much use in Season 1. However, one of the few exceptions is the ISO 9mm, which has one of the stronger SMG loadouts in Warzone.

To see the best loadout for the ISO 9mm in Warzone, keep reading my guide below.

Best ISO 9mm loadout in Warzone

• Barrel: 16″ XLB-S
• Stock: Torrent Span-9
• Ammunition: 9mm High Grain Rounds
• Magazine: 50 Round Drum
• Rear Grip: A30 Stout

This loadout for the ISO 9mm is mainly meant for sniper support, but you can also use it as a close-range option to pair with a rifle or light machine gun. I have the 16″ XLB-S barrel, which has an integrated suppressor, and the 9mm High Grain Rounds to give you a ton of extra damage and bullet velocity. As for recoil control, the A30 Stout rear grip and Torrent Span-9 take care of any bounciness when firing the ISO 9mm.

The final attachment on the loadout is the 50 Round Drum. This ensures you won’t have to reload too often, especially when fighting multiple enemies.

Best Class Setup for the ISO 9mm in Warzone

To finalize your loadout, I have the best equipment, perks, and some primary weapon options you should use with the ISO 9mm.

Primary Weapon

• MTZ Interceptor, Pulemyot 762, BAS-B, KATT AMR, or anything comparable

Perks

• Perk 1: Double Time
• Perk 2: Sleight of Hand
• Perk 3: Tempered
• Perk 4: Resolute

Equipment

• Lethal: Throwing Knife
• Tactical: Stim

And that does it for the best ISO 9mm loadout in Warzone. It might be a MW3 gun’s world in Season 1, but some MW2 guns are still worth using, and none are stronger than the ISO 9mm.
