The Beretta has to be a lot stiffer
The reciprocating mass (wt) of the Beretta bolt/carrier is significantly greater, requiring more lbs of force to overcome the inertia. Its slamming shut doesn't really mean it closes better.
the spring lbs of force between the two is about the same if viewed as unit of weight bolt/lbs of force of spring
When the weather gets cold, the Berettas cycle better and it's due to the stiffer RRS. The Benellis just plain get too slow to cycle. I was catching my stride with a shotgun as CRP was in its infancy in my native ND and I've never left. I've seen nearly every manner of shotgun fail. Beretta fails less.
