The first time I shot it was the day it came in. I put about thirty 00 buck shells through it with 3 failure to feeds and one to eject. I lubed it up and ran fifteen more and it worked fine. But still in my head something kept telling me "Hey this thing isn't fully reliable, nothing near a pump." I kept it beside neglecting my Winchester 1300 Defender who lost it's bedside title when the 930 SPX arrived. So finally I told myself Saturday morning, I am going to do a 75 shot reliability test. Mainly with full power 2 3/4 00 buck and slug shells, maybe even a few 3" shells. To my dismay, the Mossberg failed to shoot a single full magazine without a malfunction. The shell lifter would get stuck on the last shell, it wouldnt chamber a shell and i would get a "click", it wouldn't full cycle and eject spent shells. I had fully cleaned the gun and oiled it prior to taking it out for the test. I am VERY disappointed in my 930 SPX, I had super high hopes for it. Now I have to get a Mossberg rep on the line and try to send it in for whatever repairs can be done. I added a Mesa Tactical Side Saddle, Tri-Rail sling/flashlight attachment, and a Burris Fastfire red dot believing that this would be my be all end all shotgun Anyone have ideas as to what could be wrong?
