To install, you should extract archive content into the mod_overrides folder
Issues:
Barrel is floating in front of the frame. It is hardly noticeable so I decided not to fix it.
Bullets are misplaced. Again, it is hardly noticeable and it looks perfectly fine in-game so I decided to leave it as it is currently.
*As model creator said, this gun wasn't based on any particular Colt revolver but it looks mostly similar to the King Cobra and author even used King Cobra's markings so I decided to name mod as such.
