Secondary weapons, such as the COR-45 Handgun in Modern Warfare 3, have proven to be highly useful when a player runs out of their primary ammunition. To achieve the best performance with the COR-45 in MW3, here’s the best loadout, including attachments, and more.
Modern Warfare 3 offers players an extensive selection of weapons, not only including new guns but also the arsenal carried over from MW2. While ARs and SMGs typically take priority in the meta, certain Secondary weapons can prove to be competitive when equipped with the proper attachments.
Like its counterparts, the COR-45 has a unique feature that enhances its performance. With the introduction of the Aftermarket Parts, this weapon can transform into a hybrid Handgun and Submachine Gun, making it even more effective and versatile in close-quarters engagements.
So, if you’re looking to take the most out of the COR-45, here’s the best loadout including all attachments, Perks, Equipment, and more.
Best MW3 COR-45 loadout attachments

The COR-45 Aftermarket Part grants the gun a better fire rate to rival SMGs.
- Laser: KR HX-15 Laser Light
- Underbarrel: FTAC SP-0 Angled Grip
- Magazine: 30 Round Mag
- Rear Grip: Granular Grip
- Conversion Kit: XRK IP-V2 Conversion Kit
To kick off the best COR-45 loadout for MW3, we opted for the FTAC SP-0 Angled Grip improving the gun’s horizontal recoil, gun kick control, and aiming idle way as well as walking stadiness. Combined with the Granular Grip to further boost recoil and gun kick control.
Then, we equipped the XRK IP-V2 Conversion Kit which is responsible for completely changing the appearance of the weapon, in addition to significantly increasing the bullet velocity and range, fire rate, and aiming idle sway.
Finally, the KR HX-15 Laser Light helps with the ADS and sprint-to-fire speeds plus reduces the Tac Stance spread. The 30 Round Mag will allow you to avoid running out of bullets.

Best MW3 COR-45 loadout Perks & Equipment
- Vest: Infantry
- Gloves: Commando
- Boots: Lightweight
- Gear: EOD Padding
- Lethal: Frag Grenade
- Tactical: Flash Grenade
- Field Equipment: Trophy System
As the MW3 COR-45 turns into a Handgun-SMG hybrid with the Conversion Kit, Perks will be focused on boosting mobility, that’s why we chose the Infantry Vest. This will extend the duration of your Tactical Sprint and reduce its refresh time.
Additionally, Lightweight Boots will facilitate easier navigation through the maps, along with Commando Gloves to reload while on the move, enhancing your overall agility. If you’re looking to defend against explosive damage, the EOD Padding is an excellent choice.
For quick and effective elimination of opponents, consider using the Frag Grenade, Flash Grenade, and Trophy System combination. This not only allows you to easily clear buildings but also provides increased resistance to enemy bullets and equipment.

To easily level up your Operator in MW3, be sure to use Double XP tokens.
