Ingram MAC-10 -- $1400

The MAC-10 is number 3 on my list of the worst weapons, doing only slightly more damage than the TMP. This is a terrorist-only weapon. It is hideously inaccurate, and is only 100 less than the far-superior MP5. It has a 30-round clip of .45cal ammo, which does surprisingly little damage, and it can have up to 96 rounds in reserve. If you want a cheep sub-machine gun, take the MP5, not this.
