UIMPWS6400-A1 Triweapon System

The UIMPWS, short for Ultimate Individual Multi Purpose Weapon System, is the pinnacle of GRA's multi-weapon branch.
It combines a 32mm launcher, 16x63.5mm shotgun and a 5.12x45mm rifle all in one monstrosity of a gun, and is Vincent's personal weapon of choice.

Switch between the three weapons with the left fire selector, then select fire mode on the right fire selector.

It is also equipped with a 16x multivison scope, but can be removed to use other sights using the rails.

Several custom-made versions of the UIMPWS were given to the staff of PMGDF.
