Ever hear of the Bridgeport Cowboy Pistol Rig?
This non-holster was invented to be quicker than holsters.
Check out this recreation of the classic Bridgeport cowboy pistol rig.
This reproduction of the classic Bridgeport Cowboy Pistol Rig was fabricated by Youtuber bridgeportrig and is one fine revolver holder.
Unlike a traditional holster many of us are accustomed to seeing in the Old West movies, the Bridgeport cowboy pistol rig is much quicker. A stud mounted to your trusty single action revolver slides into an attachment on a belt. This allows the revolver to be quickly removed to fire. It is even possible just to flip the barrel forward and fire from the hip in an emergency.
History once again lives in this great Bridgeport cowboy pistol rig reproduction.
