JM930

Shoot a couple hundred rounds of #6, #4, or buck/slugs, and you should be fine. It just needs some break-in.

If you've already fed it 300-400 rounds of high brass, I'm gonna go on a whim and guess you didn't fully disassemble and clean the extremely annoying piston.

Not sure how true this is, but according to this website there are lots of ways that the gas piston spacer tube can foul, causing cycling issues.

Sorry to inform you, it is one big BS, in cultural words "A marketing trick", or snake oil, or whatever, aimed to just to empty your pockets.

Whatever they sell you, ether not necessary or you can do yourself in 10 minutes for $0.00 and some change.

Normally I would agree, but the the recoil tube on the new 940 looks eerily similar to the OR3gun tube for the 930. Seems like OR3gun may have been on to something with their design.

Oh yes, and what prevents you from drilling a number of holes yourself to achieve the same results and saving some dough for beer or ....

My DIY 930 upgrade.

I believe the bought version has the holes and the inner diameter is also a bit larger in the middle section for more clearance.

Mine cycles everything, given mine is a hunter version. Have you tried to clean it?
But anyways, there might be multiple reasons for gun not cycling. More details are needed.

I did not clean it prior to firing it but did visually inspect it to make sure it was lubed from the factory. Im not sure if over-lubrication from the factory could gunk up the cycling action. This is my first time with any shotgun platform so my inexperience could be a factor too.

Yes I plan on another outing with the 930 soon and a gentleman at my local GS was kind enough to gift me some of his buck shots so I am looking forward to seeing the difference and doing a detailed cleaning afterwards.

I see some holes on mine as well or my vision betrays me again, and the gap is more than enough to blow everything out. Since this mod I made at least 400 shots and it is as clean as a whistle. And I come back, those OR3 is a marketing gimmick aimed to ones who has hands growing out of their hind parts. Anyone can drill a series of holes and achieve same results.

Will do. Thank you for the guidance.
