That is exactly my point, they are beginner guns! They are utilitarian, no frills, lower price range (and be honest, the fit/finish isn't there) guns that most people can afford. Whenever someone is looking for their first auto, I recommend the 930. It's simple, good design, lower recoiling, reliable, and durable. It isn't about to take home any shooting trophies, plain as that.
Think about it, would you rather a 391 Urika Gold Sporting or a 930 field model as a general purpose gun that should last you a lifetime? Maybe you'll better understand the term beginner gun as I intend to use it (in a way that doesn't bash the 930, but certainly puts it in it's rightful catigory).
They are even moreso beginner guns to those on the clays range, lack of adjustment, bulk, and utilitarian aims put them in the beginner catigory. As stated, the 930 has potential. If Mossberg would jump in the game and ramp up the quality of the 930 and make some additions, they would beat the heck out of the 391 in my opinion.
