for the best; accuracy, power and reload time. if you hold the gun with both hands. 
your favoured hand to fire the weapon and the other supporting the gun in front of you 
and near the side "reload" button. use the transfer of weight on both hands in order to 
regain accuracy and fast shooting. while you shoot continuosly reload with the other hand.
