A Pimp Gun is:

1. Any gun that has a high polish chrome, nickle, stainless or gold finish particularly with pearl or other flashy grips. It could also be a glossy black gangster gun (Mac10 Mac11 or UZI) with gold plated parts.

2. Alternatively, any cheap chrome pistol made by Lorcin, Jiminez, or Jennings, generally worth less than $100.
