We went to shoot some trap with it today and basically the bolt will not close far enough to allow the gun to fire at all. Took it back apart and it seems the bolt is fairly smooth operating until the ejector arm contacts the barrel. Any suggestions??
Your observation that the bolt fails to close when the extractor reaches the barrel breach suggests that the barrel is not properly seated in the receiver. Follow the link below for a pdf owners manual then scroll down on that page to the 930/935. Remove the barrel assembly and forearm grip again according to the instructions, then reassemble according to the same instructions making careful notice of the illustrations. Once accomplished, the shotgun can be dry fired with a spent cartridge in the chamber –and if the hammer falls, you did it right. But hey, don’t be surprised if the 935 fails to cycle field or trap loads; they will fire 2 ¾” cartridges but for effective cycling requirements they need to be 1400-1500 fps or better. If you don’t believe me, try it.
If the same symptoms persist go to the Mossberg website and follow the instructions found under the customer service tab for returning your firearm for service or repair.http://www.mossberg.com/service/manuals
