Operation

Benelli semi-automatic shotguns operate on the same basic principle of inertial operation with fixed barrel, utilizing the kinetic energy of gun recoil, which still today represents one of the most important and ingenious innovation of sporting weapon production.

As is known this system is based on a spring placed between the locking head and the bolt.

As the gun recoils during firing, the breech bolt (inert) moves about 4 mm forward, thus compressing the spring. When this is fully compressed, it overcomes breech bolt inertia, thrusting it to the rear under residual pressure, permitting cartridge case extraction and reloading with the conventional system.

Spring pressure is designed to delay the opening of the action, which occurs after the shot has left the barrel, and to compensate for the different pressures produced by cartridges of varying power, with no adjustment necessary.

To this operating system has been added a revolving bolt head of simple and robust shape, which with only two locking lugs, closes the breech axially and perfectly, withstanding any pressure of the 12-gauge cartridge.

The new line of shotguns features a loading system designed to:

- make it possible to shift cartridge manually including 3" 1/2 shells, from the magazine tube to the barrel for quick and easy ammunition changes;

- ensure even faster and safer automatic, re-loading;

- permit rapid checking of whether the hammer is cocked and ready to shoot.
