Mastering the best Modern Warfare 3 ISO 9mm loadout is essential intel if you're looking for a weapon capable of shredding through the opposition.
Modern Warfare 3 contains an extensive list of guns and weapons but if you're after firepower armed with a fast rate of fire and plenty of mobility, the ISO 9mm is the place to go. Slotting into the SMG category, this particular weapon excels in close-range battles but at longer distances, it falls short if the strongest attachments aren't equipped.
Before we reveal more about the best Modern Warfare 3 ISO 9mm loadout, check out our walkthrough hub that's packed with anything and everything you need to know about Sledgehammer Games' latest release.

The gunsmith contains a wealth of attachments that are capable of bolstering the impressive performance of the ISO 9mm even further. After testing various combinations, this set of five is guaranteed to make an impact:
- Barrel: 9" PTX Trainer
- Stock: Torrent Span-9
- Underbarrel: XTEN TX-12 Handstop
- Magazine: 50 Round Drum
- Rear Grip: EXP Shear
To minimise any drop-off in performance when using the ISO 9mm at longer distances, the 9" PTX Trainer barrel is an excellent option. In addition to close-quarters impact, this attachment enables you to use it at longer distances.
For some recoil management, the Torrent Span-9 stock is up next. Less kick always results in improved accuracy.
Reaction times are key to succeeding in Modern Warfare 3 which is where the pairing of the XTEN TX-12 Handstop and the EXP Shear ensure aim-down sight and sprint-to-fire speeds remain low, allowing you to snap onto any incoming targets with ease.
Best Modern Warfare 3 ISO 9mm perks and equipment
Once the best ISO 9mm attachments are ready for battle, finding a set of perks and equipment along with a field upgrade is the next step to building the perfect loadout for the SMG. Here are our Pre-Season recommendations.
Perks
- Vest: Infantry
- Gloves: Commando
- Gear: EOD Padding
- Boots: Covert Sneakers
The Infantry vest enhances Tactical Sprint length and reduces its refresh rate, allowing you to make the most of the ISO 9mm's high mobility. Commando gloves mean there's no need to slow down thanks to the ability to reload while sprinting.
Up next is EOD Padding which increases resistance to non-killstreak explosives that are guaranteed to land nearby during a match. Last and by no means least are Covert Sneakers. With completely silent footsteps, navigate the map without worrying if your footsteps can be heard by any nearby opponents.
Equipment
- Lethal: Semtex
- Tactical: Stun Grenade
- Field Upgrade: Trophy System
The sticky nature of Semtex opens up plenty of possibilities when looking to deal extra damage. Stick it onto an opponent to guarantee an extra kill or onto a window frame to clear any potential snipers from the line of sight.
Stun grenades are also useful. Chuck one near a group of enemies to slow their movement and finish them off with the ISO 9mm.
For even more protection against incoming grenades, we've gone with the Trophy System as the field upgrade. It blocks up to three pieces of equipment so throw it onto the ground while capturing or maintaining control of an objective.
Is the Modern Warfare 3 ISO 9mm meta?
With such a wide variety of SMGs to choose from, it's hard to tell if the ISO 9mm will slot into the early meta. Its high mobility and rate of fire gives it superior performance over some in the category, but the lack of long-range performance holds it back.
