Best ISO 9MM Loadout in Warzone and Modern Warfare 3

The previous generation of SMGs was unruly, hard to control, and generally harder to use. But thanks to MW3 we have a slew of new weapons that have players wondering if the old guards are dead and buried. We are here to tell you that isn’t the case, the ISO 9MM is here to prove its worth. Check out the best ISO 9MM loadout below!

Best ISO 9MM Attachments

Rising from the ashes of Modern Warfare 2 is the ISO 9MM, one of the last weapons introduced in MW2 before the switch over to MW3. There are some key strengths of this gun that resemble the changes made to all weaponry in this new installment of the CoD franchise. Its high fire rate lets it chug out damage, it still has manageable recoil, and its handling is some of the best. However, a weapon born at a different age needs a few new toys to bring it up to snuff.

The best attachments are as follows:

• Muzzle: Monolithic Suppressor
• Barrel: 7″ EX Raptor-V2
• Underbarrel: DR-6 Handstop
• Optic: Slate Reflector
• Magazine: 50 Round Mag

The Monolithic Suppressor is the perfect attachment for the ISO 9MM’s strong recoil, reducing it by a decent margin while also keeping you off the minimap. To keep it up to par with other SMGs, we use the 7″ EX Raptor-V2 for better ADS and movement speeds, and then we also pair it with the DR-6 Handstop to improve recoil one last time.

Finally, the Slate Reflector is a clean optic for those who dislike iron sights and the 50-round magazine is a must-have in a Warzone environment.

Best ISO 9MM Perks

When we talk perks, we are discussing general picks, but any can be swapped out for your playstyle and preference, but for those unsure, we have the perfect package for you.

The best perks are as follows:

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

Swapping to your secondary is always faster than reloading… right? Wrong. Well, most of the time anyway, but Warzone is unique so Sleight of Hand may be the best option you can pick, especially if you’re rocking a sniper secondary. Double Time is an absolute must-have in Warzone and cannot be underestimated. We prefer Tempered in slot 3 as it gives us a faster plating time, utilizes more efficient plates, and frees up some backpack space.

As our last perk, we choose High Alert as it is a very reliable passive that warns you of enemy positions and can, more often than not, save your life.

Best ISO 9MM Attachments

MW3 multiplayer is complete chaos, objective modes like domination are constantly swapping sides, spawning on maps feels random and players are hopping, skipping, and jumping across the maps. For this reason, the ISO 9MM finds a welcome home in this fast-paced environment. It’s an SMG so it has naturally fast mobility and with its fire rate can dog enemies down before they can react. But to get its full potential we have to search for the right attachments.

The best attachments are as follows:

• Muzzle: Shadowstrike Suppressor
• Underbarrel: Bruen Pivot Vertical Grip
• Optic: Mk. 3 Reflector
• Stock: Collapsed Stock
• Rear Grip: EXP Shear

The ISO 9MM is already a fantastic weapon so we can afford to equip the Shadowstrike Suppressor that has no downsides and only the benefit of removing yourself from the minimap. For the underbarrel we use the Bruen Pivot Vertical grip to mitigate some of the recoil control lost with the Collapsed Stock. Speaking of which, this stock option turns you into a speed demon but be ready for some harsh recoil. That shouldn’t be a problem with a clean optic like the Mk. 3 Reflector and some close-quarters fighting.

Finally, we finish off our high mobility loadout with the EXP Shear, to further improve ADS and sprint-to-fire speeds.

Best ISO 9MM Perks

Perks are not what you used to know them as. We now have different pieces of body armor that give you specific and unique bonuses that you can mix and match. Mobility is the name of our game here so we are looking to equip the best perks for our game plan.

The best perks are as follows:

• Vest: Infantry Vest
• Gloves: Quick Grip Gloves
• Boots: Climbing Boots
• Gear: Tac Mask

The Infantry Vest is a must-have for any high mobility class as it offers faster Tac Sprint and recharge speed for fast rotations through the maps. Quick Grip Gloves are going to be the best gloves you can get your hands on for almost all engagements. You’ll be drawing your secondary from sprinting at blinding speeds and catching many opponents off-guard. Climbing Boots are the perfect pair for high mobility builds. Swinging around vertical engagements like Spider-Man, while negating the risk of any fall damage. Finally, the Tac Mask gives you some much-needed safety against Flashbang/Concussion equipment spam.
