If you pick up weapon you dont know nothing about magazines. Sometimes you pick up weapon with no ammo, to prevent to be easy killed you just reload it but if previous owner reloaded weapon too often you dont know that magazine is not full or close to be empty.
Also machine guns, there should be animation to check lenght of ammo belt. I mean no number of bullets just check by gunners eyes.
In conclusion how it could be: You picked up smg from ground, you are in safe position and you have time to check magazine. So you dismounting magazine and look inside to check if some ammo is here. Than you load magazine back.
