Ok but not great - GG&G Mossberg 500 & 590 Side Saddle Shell Holder

I have been using the federal mini shells with the Opsil adapter in my Mossberg 590. During some of the drills, the mini shells flip and spin when breech loading. I got the side saddle to hold full size shells for breech loading. The 1st 4 slots the full-size shells hold snug and slip out easy for breech loading. the back two slots--#5 & #6 are so tight, you can't get them out with one hand. With a home defense load of 12 minis in the tube, 1 full size chambered, and 4 usable in the side saddle, I think I have enough for a few intruders I can fumble around with the last two shells. Time will tell if 5 & 6 will loosen up with use.
The biggest issue I have is how to remove the trigger, bolt and slide without removing the side saddle fasteners--they took the place of the pin holding the trigger assembly.
