Unlike Modern Warfare where you had to complete a challenge to unlock Dual Wield, the method of unlocking Dual Wield in Black Ops Cold War is much easier!
You only need to reach level 35 of the weapon to unlock the attachment. It's only available for pistols so don't try to unlock it for any other weapons in the game!
To equip Dual Wield, Access the Attachments tab on the pistol of your choice, select "Stock" and you will find the "Dual Wield" equipment.
It's important to note that you will not be able to aim down sights when the Dual Wield attachment is equipped, drastically decreasing your accuracy.
It goes without saying that attachments to improve stability and accuracy should be used when Dual Wield is selected in order to increase hipfire accuracy.
However, if you don't have the patience to level up a pistol, you can purchase a weapon already equipped with Dual Wield in the Tracer Pack Violet Anime.
In addition to a weapon blueprint for the AK-74u and RPD, a Diamatti pistol complete with the Dual Wield attachment is also available.
Along with new blueprints, purple bullet tracers will appear on your respective weapons..
Whether in the store, via the Battle Pass or by completing challenges, there are a range of blueprints on offer in Black Ops Cold War. Find a complete list of them in this article.
