I know it's a different operating system, but what do you think of their inertia cycling system ? Just curious in that I had a friend looking at the Stoeger 20 gauge which uses a similar system and didn't have any experience in its real-world reliability.
I'm not a huge fan in general of autoloading shotguns (I like the pumps personally) and perhaps that's just because I haven't shot alot of them so my experience level and familiarity with reliability isn't that great.
I've had a Super Black Eagle that was purchased new, it's ate everything that I've fed it from trap loads to 3-1/2" goose loads without a single hic-up. I used it to duck / goose and upland bird hunt in the rain and slop. I've also shot thousands of rounds of sporting clays, before buying my O/U, and not a single failure. Some people claim the inertia system recoil is heavy, but I would argue that point all day long. My son has used it for trap and sporting clays since he was about 16, and never complained about the recoil either.
I also have an older 870 magnum, a Mossberg 500 and a Super Nova in the safe. If I could only keep one of the 3, it would be the 870. I haven't had a single issue with it since buying it NIB. It has pretty cheap wood, but I added a few coats of poly to seal it, and give it a little shine. She's not the prettiest girl, but she always goes bang.
The only complaint I have with the Mossberg 500 is the safety is a little catchy, and hard to cycle on and off. Not a problem for me, but my kids struggled with it a little when learning to shoot trap. I do like the safety up on the receiver instead of the trigger guard though. It's never failed, and has been a very reliable firearm.
The Super Nova is my least favorite of the bunch, and has been in the back of the safe for a very long time. It's one of the Super Nova's from the mid to late 90's and the forearm rattles, it's heavy, and kicks like a mule. I know some are going to say gun fit has a lot to do with how it feels, but it's the only scatter gun in my pile that I absolutely hate to shoot. (the chokes are also not compatible with my Super Black Eagle)
I've added the Limb Saver recoil pad, and even tried the recoil reducer (installed into the butt stock) without having enough success to enjoy shooting it.
Just my two cents.
