The sixth and final seasonal update has arrived in Call of Duty: Warzone and Call of Duty: Modern Warfare 2. The update delivered a slew of content to both games, including a fresh Battle Pass, new multiplayer maps, and, most importantly of all, fresh weapons to earn and level up. One of those weapons is the ISO 9mm submachine gun, which is quite similar to the ISO 45 that was released last season. However, the ISO 9mm has a much different use case and loadout in Warzone specifically.
The ISO 9mm is an extremely well-rounded SMG. It has great damage range, decent accuracy, and lightning-fast mobility. All of that is paired with a high fire rate to give you a balanced SMG that can deal damage at pretty much any range in Warzone. Of course, if you want to get the absolute most out of the ISO 9mm, you need to use its best set of attachments for battle royale modes.
To see the best loadout for ISO 9mm in Warzone, check out the guide below.
Best ISO 9mm loadout in Warzone
- Muzzle: Lacerta Compensator
- Laser: VLK LZR 7mW
- Stock: Res 2
- Magazine: 50 Round Drum
- Rear Grip: A30 Stout
This loadout delivers a little bit of everything for the ISO 9mm. You can drastically reduce your overall recoil when firing with the SMG by equipping the Lacerta Compensator and the A30 Stoud rear grip. As for mobility, you have the VLK LZR 7mW laser and the Res 2 stock to further boost your aim down sights speed and sprint-to-fire time.

The final attachment is the 50 Round Drum, which gives you all the bullets you need to take on multiple enemies at once without having to reload. It remains to be seen whether or not the ISO 9mm will break into the Warzone meta, but this loadout makes a strong case for it.
