SMG Reload Animation Not In Time

The animation doesnt match up with the actual loading of ammo into the mag. The animation stops for like half a second THEN you can aim and shoot and stuff. This makes me personally switch to my pistol after the animation, but the process isn't complete then when I switch back to my SMG there arent bullets in it and I need to do the reload animation again. I haven't spoken to anyone else on this. It is just a little thing though. Not super important. 

Basically the gun will sit idle for a second before you can use it and before the bullets actually count.
