Just came in from shooting my new out of the box (except I completely tore it down and cleaned and lubed according to my preference) Mossberg 930 JM Pro. Fired 5 rounds of Remington slugs through it to sight in the cheap Konus Red Dot sight. No issues, dialed it right in. Then a 5 box of Remington 00 Buck. Still no issues. Then a couple of boxes of cheap #8 Fiocchi ammo dove loads. Shot some rapid fire strings of 9. Flawless.Then I got out a box of old ammo that was given to me by a guy that had had the rounds since the 60's. Mixed rounds...including some paper shell 7 1/2's. Ran 22 rounds through it as fast as I could pull the trigger, I'm no slouch FWIW, and the gun was always waiting for me to fire the next round, no malfs at all.
I am posting today to confirm that while apparently there are some lemons that come off the Mossberg assembly line (like any other company), maybe a few more at Mossberg than from the Benelli factory, I am glad I went the JM Pro route (and load up on farkles and ammo with the $$$ savings). I was indeed apprehensive to get one of these based on various reports. This gun handles very well....recoil certainly lighter than my pump guns, and it looks really badass. I am not certain if it will handle everything manufactured, like the 900 fps lady defensive stuff. But I have some OR3Gun parts ordered that should take care of anything else.
After posting this originally I decided I wanted to shoot some more so opened a box of Federal Multi Purpose Walmart bulk and a box of Winchester Universal Walmart bulk. So much fun! As fast as I could shoot...Same results...no issues at all.
