I personally dont have one yet, but will be acquiring one soon. I was initially thinking about the Benelli M4, but could not justify the price. So, for my introduction into the semi-auto shotgun arena, the 930 STX is the one.
By the way, how was the initial quality? I have a Mossberg 590 and when I bought it new, I noticed all sorts of QC issues which I have, slowly but surely, been rectifying on my own.
