M1014 – Call of Duty 4The M1014 is a real-life shotgun with a semi-automatic mode that allows you go crazy with the trigger. The CoD4 version of the gun is the most power-packed shotgun I’ve seen it a long time. To balance out the the gun’s raw power and extreme rate of fire, Infinity Ward gave the gun only four rounds per clip, which means you have to reload after every firefight.
Once you get the perk 'Sleight of Hand' though, you’re in business! This perk gives you lightning fast reload speeds, so you can keep pumping your shotgun and emptying it on the enemy team. Install the grip upgrade, and the gun becomes an extremely accurate killing machine that everyone should fear. What further enhances the deadliness of the gun is its incredible pounding sound that strikes fear in the hearts of the enemy.
