That muzzle device, tho

(National Firearms Museum)

Labeled the “Combination policeman’s truncheon and extension pistol-barrel,” by its WWI-era inventor, Edward Norton Moor of Oakland, California, the device shown above is a hollowed-out impact weapon capable of coupling to the end of a revolver while still allowing the handgun to fire.

Not intended as a suppressor — an iffy prospect for most revolvers other than the gas-sealed Nagant M1895 and similar — Moor’s 1916 patent application for the device says plainly that, “The object of the invention is to provide an improved form of a policeman’s truncheon which will serve as a barrel extension of a pistol.”

Moor also registered patents on a number of other barrel extensions in the U.S. and France, as well as a fishing pole. (Photo: Google Patents)

I can’t find a reliable source for just how many of Moor’s devices were made, but, at least a few examples were produced by the Automatic Screw Company in California, with a 1919 patent date.

About laststandonzombieisland

Let me introduce myself. I am a bit of a conflict junkie. I am fascinated by war and warfare, assassination, personal protection and weaponry ranging from spud guns and flame throwers to thermonuclear bombs and Soviet-trained Ebola monkeys. In short, if it’s violent or a tool to create violence it is kind of my thing. I have written a few thousand articles on the dry encyclopedia side for such websites as Guns.com, University of Guns, Outdoor Hub, Tac-44, History Times, Big Game Hunter, Glock Forum, Firearms Talk.com, and Combat Forums; as well as for print publications like England Expects, and Strike First Strike Fast. Several magazines such as Sea Classics, Military Historian and Collector, Mississippi Sportsman and Warship International have carried my pieces. Additionally I am on staff as a naval consultant and writer for Eye Spy Intelligence Magazine. Currently I am working on several book projects including an alternative history novel about the US-German War of 1916, and a biography of Southern gadfly and soldier of fortune Bennett Doty. My first novel, about the coming zombie apocalypse was released in 2012 by Necro Publications and can be found at Amazon.com as was the prequel, Chimera-44. I am currently working on book two of that series: "Pirates of the Zombie Coast." In my day job I am a contractor for the U.S. federal government in what could best be described as the ‘Force Protection’ field. In this I am an NRA-certified firearms, and less-than-lethal combat instructor.

    To what purpose?

  2. mobiuswolf says :

    I guess it’s a thing. I remember when van Cleef pulled out that three foot revolver. It was a big hit.

    • Secundius says :

      Not exactly! van Cleef had two Colt SA Army “Bluntline Special” .45 LC Revolvers in the movie. An Bluntline with 18-inch barrel in his Saddle Bag and a Bluntline with 10-inch barrel fitted with a Stock that he carried with him…

  3. Secundius says :

    Are these Barrel Extensions still being produced? I can see there potential usefulness in a BOB kit where Minimum needs can be Maximized
