Some of the problems might just be teething pains in a new design, but design flaws are another matter. It would be nice to have another dedicated and capable semiauto fighting shotgun on the market, but it seems Mossberg has trouble getting it right.
FWIW, YMMV, etc-

Mossberg 930 Shotgun
19 Nov 07
Mossberg M930, Autoloading Shotgun:
During an Urban Rifle/Shotgun Course in OH last weekend, a student brought a brand-new copy of Mossberg's M930 Shotgun. It is the first one I've had a chance to actually use and observe on a range.
Bottom line: The 930 is unusable for our purposes.
Problems became apparent immediately as the student attempted to manipulate the gun. Once loaded, the entire magazine tube must be completely voided and then subsequently recharged all over again, in order to return the shotgun to Transport Mode (magazine tube charged, hammer down on an empty chamber, manual safety "off," Transport Mode is often referred to as "Cruiser-Ready" ). In addition, when attempting the load the gun, it continually double-stacked, causing two rounds to be released from the magazine tube into the receiver, simultaneously.
After ten, frustrating minutes of attempting to come up with a viable handling procedure, we gave up and issued the student a Remington 870, which, of course, ran fine for the duration.
Some years ago, Mossberg produced another autoloading shotgun, dubbed the " Jungle Gun." Now long-since out of production, we had nothing but trouble with it too.
Mossberg is surely capable of producing functional shotguns, but this new 930 is utterly unsuitable for our purposes. Again, when making ostensible " police" shotguns, they need to talk with someone other than trap shooters!
