Patriot converted directly from Metal Gear Solid 3: Snake Eater.

The model and texture are original, both extracted directly from the original game folder. In addition, every effort was made to realistically allocate the weapon in CJ's hands.

As of now, it is technically impossible to extract and convert the original weapon icon for GTA SA.

Original description of the Patriot in Metal Gear Solid 3: Snake Eater:

An assault pistol developed for The Boss. Uses 5.56mm x 45 ammunition. The feeder mechanism inside the drum magazine forms an "∞" shape.
