tnxdshooter,
and here I thought this was The High Road.
I do own horses though and recognize the difference between what I personally have seen in a class from Morrigan Consulting that included LEOs and DOD folks besides private citizens and that which you referenced.
What I saw was side saddle type mounts failing and dropping rounds during movement.
Your experience may be yours but mine is mine and no less true.
As an example in my experience a pistol grip on a Mossberg 500 is a bad idea because it negates the advantages of the tang mounted safety. You seem to feel otherwise and I feel no desire to make ugly comments on your choice. I like the idea of having a standard stock on an entry gun or HD gun because it gives me the feeling that I have more options short of shooting in that I trained in bayonet fighting before it became "instinctive" and so learned to make extensive use of the butt of a weapon as a weapon and I would not feel comfortable doing so with a sliding AR type stock. Again I see no need to get nasty and call your opinions something I spread on my garden.
On the other hand if you gave me your Mossy I personally would remove the side saddle and find a traditional Butt stock for it (perhaps a Youth stock if I was going to be using it primarily with heavy body armor) but I respect your decision to set up your gun as you choose.
Aren't those Ghost ring sights about the neatest thing ever put on a social shotgun? I really like them. Mine were dead on at 75 yards with the foster slugs I was using when I got mine, but I called Mossberg to ask about adjusting them so I would better understand how. The asked where it was shooting and when I told them they simply asked why I would want to adjust the sights and left it at that.
