If you try using the new weapon swap animation, it's possible to still shoot in the process, which can cause you killing your victim, or even potientially killing yourself (killing yourself happens most of the time)

This will happen, if you want to try and shoot and your target right away, and are holding the aim button, and spamming the fire button, while in the middle of the weapon swap animation (hoping to kill your victim as soon as possible), but instead you get bugged out, and probably will kill yourself instead.

Also, you can still instant swap to your weapon, if you are holding something in your hand other than just nothing, but fists out (examples: beans, mags, maps, radios, all items in hands), you can just swap instantly to your weapon, bypassing the animation, which is very exploitable.
