The X13 Auto is a reliable sidearm in MW2, and its best loadout will provide you the accuracy and control to finish off your enemies.
Each weapon in Call of Duty: Modern Warfare 2’s handgun category is extremely useful. These sidearms can act as your main source of damage or ensure your kill if your primary runs out of ammo. The X13 Auto, with its best loadout attached in MW2, does wonderfully in either role.

As the name implies, the pistol is automatic. It unloads a barrage of bullets that most enemies won’t expect when they see you swap to your sidearm. The X13 Auto will be a very accurate companion to whatever larger weapon you utilize alongside it.
How to unlock the X13 Auto
The X13 Auto is part of the XRK Weapon Platform. It shares the progression tree with the X12 pistol. After you’ve unlocked the X12 by reaching Military Rank level 31, you can begin the process to unlock the X13 Auto.
There are no challenges that require a certain amount of eliminations or crazy shots you have to land. You just need to bring the X12 to level 10. Do this by simply getting kills with it in any of MW2’s modes and you’ll have the X13 Auto in no time.
