The Welrod

Cold War, Custom builds, Suppressed, Weapons, Welrod, WWII

A client recently contacted me and asked about the feasibility of building an Airsoft Welrod. This is a project I have wanted to do for some time so I came up with an initial design within three days and have revised it a little since then.

Anyway, a brief history of the Welrod is in order:

Design and Variants

By the Second World War, the science of suppression was pretty established. Suppressors had been made for the Maxim gun and were available for automatic pistols. However, the noise of the action cycling was an issue with suppressed automatic pistols and British clandestine forces (and indeed Resistance movements throughout Europe) required something more discrete.

The answer came from Major Hugh Reeves of the Special Operations Executive’s Station IX, where a great number of novel inventions came to life. He designed the rather ugly Welrod Model 1. In .32 ACP this design had a few shortcomings:

  • Magazines had to be loaded through the ejection port one round at a time
  • The pistol grip, though short, made the gun an awkward shape to carry
  • The trigger was a thumb-activated push-switch in the left of the gun, meaning that accuracy was impaired through a loss of purchase

Just to confuse you, there is also a MkI Welrod, which looks a little more like the pistol people recognise today:

Featuring a trigger guard for the more conventional trigger and a grip safety, this design had many features that appealed to the end users. It did however still look a bit gun-like, which for secret operations isn’t greatly desirable!

So, a re-design was in order and led to the MkII and MkIIa. This is the Welrod people recognise, it uses the magazine as the grip and is a simple bolt-action using a knurled round grip to operate it rather like the MkI.

Due to the removable nature of the grip magazine, this version was significantly easier to hide, the main body of the tube was affectionately named the ‘bicycle pump’ for obvious reasons. When taken apart it could easily hide in a cyclist’s pannier or a plumber’s toolbox and be quite unidentifiable to the untrained eye, made less obvious by the deletion of the trigger guard.

The MkII/a was available in .32ACP and, perhaps more sensibly on the continent, 9mm Parabellum, the standard round of many German submachine guns and handguns.

The nature of the suppressor is also definitely worth a mention here. As well as the usual close-fitting metal rings found in a normal suppressor that eliminate various pitches of sound, the Welrod contained a number of rubber washers with a hole in the centre, just *slightly* smaller than the round that passed through it. This makes the suppressor extremely effective, if a little less accurate! Most Welrods were measured to make about 73db of noise.

 Service History

Obviously a weapon designed for secretive use such as this gets little mention in the annals of history. However, there are suggestions that as well as extensive use with the SOE and Resistance movements through Western Europe, a US version saw service with several of their forces in the Far East not only in WWII but also possibly in Vietnam. Some sources suggest that Welrods were used as late as the 1991 Gulf War by British Special Forces, as well as in Ireland and the Falklands.

If any of you are familiar with the stay-behind units of NATO designed to slow down and harry the Soviets in event of war (Gladio teams), Welrods also featured in their weapons caches.

So much of this is of course, somewhat speculative. There are many rumours and tall tales about who was issued these unusual guns, and they add a romance to a story that a suppressed Browning Hi-Power just doesn’t quite carry…

  1. Hi,
    I am interested in purchasing a welrod airsoft pistol from you if you can make one. Specifically a Mk1. Please contact me at my email. I would like to discuss the build of the pistol.


    1. Hi Erik, thanks for getting in touch and sorry for the delay in getting back to you!

      I’m still working on a usable design that looks the part. I’ve dabbled in CO2 and wasn’t happy with the outcome. I tried a spring mechanism a log time ago and didn’t get the desired results, I’m now working on a new spring mechanism that holds some promise.

      I’ll post further when I have something to show, in the meantime join me on Facebook as I post smaller updates on there.
