After updating BF3 for my Xbox, there are two 93R pistols and two .44 Magnums in my inventory.

Here's more detail. I updated my game on Xbox and in 'My Soldier' there was a marker for something new. I looked at it and it is another 93R and .44 Magnum that I can equip. I went onto an empty server and tried them, but there's nothing visually different. Could they be added in as a mistake, or is it for something to happen in Aftermath?
