Rizzini double rifle part 3
      07/07/23 07:11 PM

Without further ado here is an "infographic" of the lockworks of a Rizzini BR-550E.
The design is typical Val Trompia trigger-plate with the addition of a hammer blocking wedge
that prevents firing if the sears fall off while the safety is on (as if you dropped the gun).
The function is similar to a best gun side-lock sear blocking safety but this design is much simpler and easier to manufacture.
My Beretta double 12 ga. have no such feature at all.

1-Safety on, hammers cocked


2-Safety on, right sear pushed off, hammer blocked


3-Safety off, right sear engaged


4-Safety off, trigger pulled, right barrel fired


5-Right barrel fired, safety back on, sears dropped as with firing inertia (recoil)
Hammer block no longer effective for left side.


6-Right barrel fired before recoil


7-Right barrel fired after recoil


8-Left barrel fired


9-Left barrel fired, safety back on


I'll have more on regulating some non-factory rounds in the next installment.
