The HRM-9 stands as one of the additions to the submachine gun arsenal in Modern Warfare 3, and there are indications that may it be overpowered.

The new SMG boasts several advantageous features, and many players have found the HRM-9 to be exceptionally effective in the game.
The absolute best HRM-9 loadout to shred in MW3
Let’s dive into which attachments make the HRM-9 a truly overpowered weapon.
We begin with the Folding Stock for enhanced recoil control and improved fire aim stability.
Since this build won’t be running a barrel, the XTEN Phantom-5 Handstop is brought in to help with improving the recoil along with sprint-to-fire and aim-down-sight speed.
Another attachment to help the lack of a barrel is the 9mm High Grain Rounds. These will help to increase bullet velocity and damage range. These will be loaded into a 50 Round Drum.
Finally, you can optimize recoil and stability while being harder to spot on the radar with the ZEHMN35 Comensated Flash Hider muzzle attachment.

- Underbarrel: SL Skeletal Vertical Grip
