9mm autoloader

The 9mm autoloader or Colt 6504 9mm autoloader is a weapon that was to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios. It also featured in the Van Buren tech demo.

Background
This gun is apparently the predecessor to the Colt 6520 10mm pistol, which saw more widespread use in New California.

Characteristics
The Colt 6504 9mm autoloader is a good weapon to use when you get it. It allows you to take ranged shots, which can be pretty helpful if your action points are low. However, due to the nature of the battle engine, remember to move your character away from the target, or else he'll keep on firing without moving.

Weapon modifications
Unused models and icons in the tech demo's files indicate that it could be modified with an extended magazine, a silencer, or both.

Locations
