Term used primarily in the hip hop community to describe the Desert Eagle .50 cal handgun. Fully loaded, the Desert Eagle weighs approximately 4 pounds. This term is often wrongly used to describe a wide range of 9mm or .45 cal handguns which weigh much less than 4 pounds relatively. For instance, a fully loaded Glock 17 weighs 31.91 oz, just under 2 pounds.

The term "four pound" refers to a .45 caliber handgun literally meaning four plus a pound.

i.e. four---->(4) pound---->plus a pound(4+1=5) = 45

Desert Eagle .50cal??? Are you kidding me? NO! It means a .45.
Fuck a 9 or .40cal you need a four pound if you wanna really put a hole in a mother fucker.
