The same probably goes for semi-auto rifles and shotguns. I’ve never seen any such chart, but I would hope that some testing laboratory somewhere has (or soon will) put one together. I wonder if anyone has ever compiled measurements of various semiauto pistols (shooting various pressures and bulletweights of ammo) that determined the minimum recoil-resisting mass/force necessary to properly cycle the action when fired semi-to-fully “limp wristed”? Ironically, the gun that ended up replacing the rock-solid revolver was the thermoplastic-framed “polymer” pistol, which due to the laws of physics had to be even less “hip-firing friendly” than the traditional heavy steel pistol. “attempting a quick draw with a loaded and cocked Browning action pistol and then rapidly firing from the hip Wild West style will increase the chances of either stove-piping or extraction failure…”Ībsolutely, and that’s one reason why the convention wisdom here in the US for perhaps most of the 20th century was that this intrinsic “limp-wristing” failure of semiauto pistols made revolvers a safer choice for self-defense use, since they could be fired from the hip with near-100% reliability. Browning that were, at this time, still in force. So there’s the Iver Johnson connection.Īlthough visually interesting, this appears to be just another failed attempt to design a pistol around the constraints put on the industry by the various pistol patents by John M. Johnson is identified as the “executrix” to Iver Johnson, (either the man or the company or both). You’ll note that this patent is assigned to Mary Elizabeth Johnson, trustee.
Cobb worked for the Iver Johnson company and has other patents assigned to that company. It also appears to do away with the “wedge” holding the barrel to the frame, replacing it with a couple screws.

So, the more finished example probably has a more conventional single-action trigger with a full cock notch, thus the addition of a safety. I’m going to guess that this firearm would double, or go full auto.

So, there is no need for a manual safety since the hammer is never in a full cock condition. The patent describes a double-action-only, hammer fired pistol where the hammer follows the bolt down between shots.
I wasn’t able to find a patent for the changes made for the more finished example. You’ll note that this is for the rough, prototype pistol.
