US Army Experimental Full Auto M1911

A photo of the ultra rare full auto 1911 that was being developed for WW2. You can see some of the extra parts and the beefier slide to help keep everything from shooting itself apart under the higher cyclic rate. Also is the extended magazine. Seven rounds won’t go far under full auto.

The rear sight is pretty interesting.

  1. It is curious that there have been so many of these full-auto pistols like the MAC-10 and the Glock 18. It seems to be a niche that doesn’t need filling.

    • It is weird how every decade people get the itch for a full auto pistol then a few things pop up and then everyone remembers they kinda suck for any serious use. then forget and 10 years or so pass and some one gets that itch again

      • There’s a lot of that in gun design circles. Lots of people say “Why not do X? or “Why not cartridge C?” or some other such thing, and then some killjoy (such as yours truly) comes along and says “Oh yea, someone’s been there, done that…”

        My favorite area in this matter are big magnum cartridges. Ranting against new, niche cartridges is my semi-favorite pastime in guns. There are damn few new cartridges that are a significant enough improvement to merit consideration by a gun buyer. When we look at modern “dangerous game” cartridges, one can look back at such beasts as the .404 Jeffery, the .505 Gibbs and others and ask “What? These weren’t enough for you? OK, so what about a .416 Rigby?”

        “But, but, but… they’re old… I want the new hotness!”

        Sigh.

        But back to machine pistols. If they were such a hot lick. they would have taken off over 100 years ago, when Steyr fielded the very first one. The idea has come back around about every 10 years with regularity, war or no war, ever since then. The MAC-10/11, with a real suppressor and heat shield, might have been the best of these ideas because it was cheap, simple and it worked, but even then, the portability is rapidly going down, while you’re gaining little on a regular handgun.

        That said, in my mind’s eye, I can see what that auto-sear/disconnector setup milled into that slide is doing on that 1911. Nice idea, but it would not resist much dirt or muck.

      • The Glock 18 and the Beretta 92 variant are the last two that I can think of, and that’s been almost 40 years ago. What has there been since then?

        It kind of feels like the switch away from the subgun among door-kickers has really put the last nail in the coffin on these full-auto pistols.
