Got mine today and I must say it is much tighter put together than my previous Grizz. Gave it a wipe down and tried running some shells through it...LOTS of FTE and FTF's. I was thinking WTF? Anyhow, took it apart and lubed the crap out of it and racked the action a couple hundred time...she works much better now on the 2 3/4 shells. The big bad boy 3" shells seem to be more problematic...it's almost like they barely fit...and the last one from the tube mag will jam halfway on the lifter. Now this is all without firing it (but my previous Grizz, KSG, and 590A1 don't do this...I know, apples to oranges). If I keep a 2 3/4" in the last position it'll feed fine but there's a 50/50 chance of the 3" shell jamming on ejection. I'm wondering if the mag tube spring is weak? (just spit ballin' here). I won't be able to compare it to my previous Grizz until my son gets back next week from training. Thoughts/suggestions? Or maybe just forget it about it and see how it actually runs when I'm at the range...
