The Season 1 Reloaded update introduced a new submachine gun into Call of Duty MW3 multiplayer. The HRM-9 is a fast-firing, high-risk high-reward weapon that needs some work if you want to use on the medium to larger maps. Luckily, I have a strong loadout for the HRM-9 that makes it unstoppable in MW3.
To see the best loadout for the HRM-9 in MW3, keep reading my guide below.
Best HRM-9 loadout in MW3
- Muzzle: Purifier Muzzle Brake S
- Barrel: Princeps Long Barrel
- Stock: Folding Stock
- Underbarrel: Bruen Heavy Support Grip
- Rear Grip: PCS-90 Assault Grip
As the HRM-9 has plenty of recoil by default, the main focus of this loadout is to make the SMG more accurate when firing. This is accomplished by equipping the Purifier Muzzle Brake S and the Bruen Heavy Support Grip. Both of these attachments massively cut down on recoil and add some stability to the HRM-9 as well. The Folding Stock and PCS-90 Assault Grip are also in place to help with both of those stats.

The final attachment on the loadout is the Princeps Long Barrel, which offers extra bullet velocity and damage range. While you won’t be able to take on many assault rifles at range, this attachment gives you better odds at killing enemies from farther away.
Best Class Setup for the HRM-9 in MW3
The last step to completing your loadout for the HRM-9 is to add the remaining class elements, such as the equipment, Field Upgrade, and perks.
- Gloves: Assault Gloves
- Boots: Tactical Pads
- Gear: Tac Mask/EOD Padding/Ghost T/V Camo
- Lethal: Semtex Grenade
- Tactical: Stim
- Dead Silence
And with that, your HRM-9 is complete and it’s ready for action in MW3 multiplayer.
