I can tell you this, took the Affinity down to clean after nearly 3 full boxes of steel loads, nothing in the receiver, 2 specks of powder in the barrel, mag tube clean, ran a bore snake thru it and reassembled.
I have had the A300 Outlander and it was a fine shotgun, just nothing compared to the Affinity. The Affinity is lighter and trimmer, easy to clean and has 4 plus yrs warranty over the Beretta.
The Affinity has 5 shims and you never have to remove the butt stock to clean it.
