I am now satisfied with mine but before recommending it to anyone else I would have to tell them what I went through to get there - complete internal polishing and weld the lifter and smooth the loading opening - oh and a minor detail - I had to bend the barrel to hit point of aim.
No it is not satisfactory - it is crap, but now mine works and as long as it does it is good enough - would not do it over again - except, I really like the light recoil - the fast loading and the excellent pointability. I run into folks all the time that have problems with theirs and we can get them working in all cases so far.
Mossberg really does not appreciate its customers.
