Re: Brand New Mossberg 930 Owner we have a problem
I think if you check out the 930 portion of this site you will find that these problems do in fact exist (and many more) and you are not alone. The spring / extension problem is the most prevelent.
However, many people have called customer service and requested to send the whole shotgun back for warranty work. I think it is fair to say that given time and patience, Mossberg will do the right thing and get you the SG back and working properly.
Mine is at Mossberg right now - without shooting the first round down the tube - hoping to see it back late this week or early next week. They offered me a spring, but I had other issues also so opted to return the whole thing for a do-over.
If the spring takes care of the problem, great, otherwise - 1) clean it thuroughly, 2) put some rounds thru it (100+) 3) assess everything from the sites, to strange wear and scratches, to how the elevator allows shells into the magazine tube, to how many rounds it takes, etc (read the trouble shooting portion of this site COMPLETELY to understand everything I am talking about). 4) Send it back to Mossberg for warranty, 5) be patient. I think most owners have had good results after 1 or 2 rounds with Mossberg.
There are a lot of guys out there who are really happy with their 930. i hope you and I will be 2 more.
Oh, and in the end, the Nortic extension, and a wolff spring, and a replacement follower may still be needed for flawless performance. $700 is about the price of admission.
One guy talked about polishing the inside of the mag tube, polishing every edge he could find to improve the reliability - some say just put a crap load of rounds thru it to break it in - his thinking is that polishing speeds it up.
