personally im getting pretty sick of hearing Mossberg parrot its
'the only shotgun to ever pass the US Army's Mil-Spec 3443E test' bullsh*t over and
over again in their marketing.
they neglect to mention that it was also the only shotgun ever submitted for testing
~$300 short barreled shotgun: buy a Grizzly. its the best bang for your buck going. all metal parts, better machining than an 870 Express, shorter barrel (out of the box) than youll find on anything from Remington or Mossberg.
id highly recommend the 870 platform as a first shotgun. it is hands down the most versatile and popular platform. if theres something you dont like about it, you can visit the EE or just about any gun shop in North America and remedy it -- or change the gun into something completely different. the Mossberg 500/590 is also a great gun and
almost as versatile, albeit with less parts and accessories available on the EE.
id definitely stay away from anything other than these, however, as they have virtually nonexistant aftermarkets and lack the steady flow of used/take-off parts in the EE.
