Soldiers tend to ditch unreliable weapons, as they don't wont to be in that situation were you pull the trigger, and all you hear is "Click, Click," Soldiers are trained to go through their AI's when a weapon stops working, but if the weapon falls outside there training expectations, you find another one quick!!
When your life is on the line, you want certainty, and if that means double tapping the enemy, then that how it is.
