Dual Beretta 96G -- $1000

These guns are very popular with some people, but not with me. Each gun holds 15 rounds of 9mm ammo, making 30 ammo total, with 100 in reserve. While your ammo might outlast your opponents with these guns, they are not terribly accurate, especially at long range, and they cost a lot more. They are also only available to the Terrorist team. Personally, I think they are not worth it, and can do much better with the cheaper Desert Eagle, but some people like them.
