Having featured in almost every prior Modern Warfare game, the Uzi was greatly missed in MW2. It has now made a return in MW3 and we’ve put together this best WSP-9 loadout to use in Modern Warfare 3 to help you get the most out of it.

Last appearing in Modern Warfare (2019), the Uzi returns to Call of Duty this time as the WSP-9. This 9mm SMG sacrifices fire rate for accuracy and range resulting in easily the most versatile submachine gun in MW3.

In the right hands, the WSP-9 is capable of competing against assault rifles from afar thanks to its impressive accuracy. However, it doesn’t have the fastest TTK in the game so you’ll need to hit your shots or risk getting outgunned.

We have you covered for the best WSP-9 attachments, perks, and equipment to use and get the most out of this highly adaptable SMG in Modern Warfare 3.


Best WSP-9 MW3 loadout


  • Barrel: WSP Infiltrator Integrated
  • Laser: VLK LZR 7MW
  • Optic: Slate Reflector
  • Stock: WSP Factory Stock
  • Magazine: 32 Round Mag

With the enhanced movement in Modern Warfare 3 it’s best to build SMGs to be snappy while still making sure they can still hold their own at range. This is an area where the WSP-9 excels so it’s important to not waste that.

While integrated barrels were rarely useful in MW2, the WSP Infiltrator Integrated is a great option in MW3 giving the WSP-9 an integrated suppressor that will keep you off the radar while also improving its recoil.

To make the WSP-9 as mobile as possible it’s best to run the WSP Factory Stock and VLK LZR 7MW laser. When used together these massively improve handling keeping the Uzi feeling like an SMG despite its assault rifle-like range.

The WSP-9 comes stock with just 25 Rounds which can be difficult to work with and leave you constantly reloading, but the 32 Round Mag fixes this problem. Finally, the Slate Reflector is a clean all-around optic that is worth using as the WSP-9’s iron sights leave a lot to be desired.

Best WSP-9 MW3 class: Perks & equipment

  • Vest: CCT Comms Vest
  • Gloves: Assault Gloves
  • Boots: Covert Sneakers
  • Gear 1: Ghost T/V Camo
  • Gear 2: Blacklight Flashlight

The CCT Comms Vest causes enemies you kill to drop intel packs, which generate radar pings revealing other nearby foes. It also increases the duration enemies stay on radar which is extremely strong when running around with a UAV active.

A big benefit to this vest is it provides four equipment slots: Gloves, Boots, and two Gear, although this comes at the cost of both lethal and tactical grenades. For Gloves, the Assault Gloves are recommended which enable aggressive jump shotting by improving accuracy and ADS time while mid-air.

Meanwhile, Covert Sneakers are a must for the boots slot as they silence footsteps letting you flank enemies much easier. This partners well with Ghost T/V Camo which hides you from enemy radar pings, combining with the suppressed barrel to create the perfect stealth loadout.

The second Gear slot can be adjusted to suit your preferred playstyle but Blacklight Flashlight has great synergy with the WSP-9 as you can track down enemies by following their footprints, using this SMG’s high mobility to your advantage.

How to unlock the WSP-9 in Modern Warfare 3

The WSP-9 is unlocked as an Armory Unlock at Level 25. After reaching Level 25 you’ll need to activate the WSP-9 and then complete 3 daily challenges. Alternatively, successfully extracting with a WSP-9 in Zombies will also unlock it and skip the grind entirely.

Best WSP-9 alternative in Modern Warfare 3

The Striker is another slow-firing SMG that is extremely accurate while still having a competitive TTK. Alternatively, those willing to use MW2 weapons should consider the Vaznev-9K which retains the WSP-9’s excellent mid-range while also having a faster and more forgiving fire rate.
