There are four new secondary pistols in Call of Duty: Modern Warfare 3 multiplayer, and only two of them are viable for most situations. One of the choices that is viable, alongside the Renetti, is the COR 45, which has a fantastic loadout in MW3.

The COR 45 is a classic semi-automatic pistol that fires as fast as you can pull the trigger. However, like plenty of other weapons in MW3, the COR 45 has access to a Conversion Kit, which grants you the ability to double-tap the pistol. This opens up a ton of opportunities to use the COR 45 in different ways, but you need the best loadout for the pistol to make the most out of it.

To see the best COR 45 loadout in MW3, keep reading the guide below.

Best COR 45 loadout in MW3

  • Muzzle: Corvus Series D
  • Stock: ARK Dynamic Precision Stock
  • Underbarrel: XTEN Phantom-5 Handshop
  • Magazine: 30 Round Mag
  • Conversion Kit: XRK IP-V2 Conversion Kit

The loadout is designed around the XRK IP-V2 Conversion Kit, which grants you a better fire rate and recoil control in exchange for less damage and mobility. As previously stated, the kit makes it so the COR 45 double-taps every time you fire, meaning you shoot two bullets instead of one every time you pull the trigger.

To compensate for the extra bullet, I have added the 30 Round Mag as well as a couple of attachments that boost recoil control so you can stay on target at longer ranges. I have also improved mobility with the XTEN Phantom-5 Handstop, which also slightly boosts recoil control as well.

If you don’t want to use the Conversion Kit on the COR 45, then I suggest replacing it with a barrel, as this should improve damage range. You could also opt to not run a stock and instead go with a trigger action to increase the pistol’s fire rate.

And that does it for the best COR 45 loadout in MW3. It uses some strange attachments and doesn’t behave as it normally does, but the Conversion Kit is a game-changer in multiplayer.
