Weapons Tip - Use a pistol instead of reloading | Call of Duty: World at War
It is sometimes a good idea to get used to the idea of whipping out a pistol when in a fire-fight if you have to reload. Obviously this depends on the range at which you are fighting the enemy, though reloading should not be a huge problem if you are having a 200 metre rifle stand-off. As soon as your current magazine runs out of bullets, or even as it's getting low, hit the change weapon button (Y or Triangle) to pull out a pistol. Aim down the ironsights and get some crucial shots on the enemy to both do damage and prevent them from hitting you accurately. It's worth remembering however that you can pick up a new primary weapon at any time to replace your pistol, thus giving you two very good options, even if you don't have Overkill.
