I'm trying to picture a handgun that works along Benelli's inertia unlock principle. The advantage would be fixed barrel and a very strong locking action. Let me know what you think.
From the outside the inertia operated handgun would look like a conventional automatic. There are three main differences:
1. There are two seperate springs, a conventional recoil spring, and a larger inertia spring which wraps around the former.
2. It use a two lug rotating bolt which locks into the fixed barrel. When the gun fires the bolt remain locked to the barrel until the blowback subsides.
3. The slide is free to move forward a fraction of an inch.
When the gun is fired it begins to recoil, but the heavy slide resist this motion by staying put briefly. Therefore like the Benelli action, the slide compresses the inertia spring, which kicks the slide rearward. The bolt would have a curved cam track which the retreating slide catch and rotates.
With the bolt unlocked residual pressure forces the bolt back along with the slide, completing the case extraction sequence. Finally, like a conventional automatic, the recoil spring acts to pull the slide forward, picking up a fresh round, and locking the bolt into the barrel.
