I have a problem with my Grizzly...
When cycling it the bolt catches the shell, but then the feeder doesnt push it up all the way into the chamber... This is intermittent.
Also the pump get's stuck when fully extended (bolt closed) after firing. This is also intermittent.

Used Winchester 2.5" 7 1/2 shot. Also had this problem with 3" 00 Buck and 2.5" 1oz Slug.

I had the same problem with a friends mag fed grizzly. The issue was the action locking bar ( the same tab you push in to unlock the action ) was out of line with the sliding bar coming back from the pump. When it works properly, the end of action locking bar pushes against the end of the bar coming back from the pump, not allowing the pump to slide back under recoil. In my case, the two bars were sliding past each other and then getting jammed, allowing the bolt to move back slightly first. I had to ram the pump forward to clear the jammed bars.

You can check if you have the same issue by (gun unloaded of course) by cycling the action and watching through the bottom how the bars line up. Using a vice, and a hammer/punch, I had to put a slight bend in the bar coming back from the pump to get them to line up again. Too much bend it the action is harder to cycle though, so tread carefully. Problem seems to be solved now.
