I don’t like the M-9/92/96/etc guns because when you detail strip them, plungers, detents, springs, etc tend to go sailing off the bench. They’re spring bombs, in other words. They also use roll pins, which... aren’t what I want to see in a quality firearm.
The Beretta line of shotguns is quite good. Absolutely nothing wrong with their semi-auto shotguns or their double-barreled shotguns.
Up until the late 1990s, SIGs used roll pins with out issue.
But, I agree about the spring bombs. I used to vacuum up my shop just to filer through the trap to find all the springs I’d lost.
