Hogue Avenger: Precision Accuracy Via Delayed Blowback

The Avenger is a flapper-delayed blowback, fixed barrel conversion upper assembly for the Model 1911 pistol. It was designed by Austrian Peter Spielberger, and manufactured by Hogue in the US and PowerSpeed in Austria. It is a product that came close to vaporware status, announced at SHOT Show in 2003 but not actually available until around 2011 – and by then at nearly double the initial advertised price.

The Avenger is a very well-made system capable of fantastic accuracy – but it was a commercial flop. It was too expensive, and didn’t offer sufficient practical benefit over a simply well-tuned 1911. It went out of production almost as soon as it was made available, and is quite scarce today.


      • It’s a mechanical disadvantage delay. The more the slide surface is inclined in respect to the “locking lever”, the more the recoil force is directed towards / absorbed by the frame. At 90° the action doesn’t open any more due to recoil.
        The Bernardelli Victor shotgun used a similar system (but in the form of a modified SVT-40 tilting lock action, but with the aid of the inertia-driven bolt carrier, to ensure opening even with light loads.

      • Obregon is recoil-operated, however unlike M1911 locking is achieved by rotation (along barrel axis) rather than tilting

      • Oh, sorry, I thought you were talking about the Avenger, not the Obregon.
        The Obregon is rotating barrel locked, like a Steyr 1912 or a Beretta PX4. Not to mistake with rotating barrel delayed, like the Savage 1907 or the MAB PA-15.

  1. It seems what happens when a designer falls in love with an idea, and spend his time and resources to make it work, ignoring the other considerations.

    To me, the easiest way to make a 1911 fixed-barrel delayed-blowback is to make it gas delayed, since the gas piston simply takes the place of the spring guide rod.
    Chiappa also, about 10 years ago, shown a prototype of a “Steyr GB” style 1911, a blowback that uses gas as recoil pad.
    The 1911 having a barrel bushing already (here enlongated) makes it particularly apt to this solution.

  2. The Australian Army had the good sense to stay with the Browning GP35.
    I was issued one along with the Land-Rover 4WD and an M16 tucked under my legs.
