Ha, I handled the 28" Super Black Eagle yesterday.Benelli has 24 BlackEagle, Prophet River special ordered for from States
I also handled the Browning Maxus 2 and Beretta A400. The Benelli felt the lightest / most compact IMO. Hard to make a call from a minutes worth of handling in a store however.
I have watched some reviews and they are all over the place with one person stating that they went from a 1301 (gas gun) to a Stoeger (inertia gun) and found they could run way lighter loads with no issues, then another completely flips that on its head saying that they found that the Beretta would run anything and the inertia gun (forget which, might have been a Browning) was much more fussy / less reliable.
I know that inertia needed to be handled / held a certain way to make it function properly (needs to be solid / held firm - no loosey goosey) so maybe that is a factor.
