Jealous? Me?
Heck,no. I've shot lots of Mossbergs, even owned a 500 long ago. Good gun, but I prefer the various 870s I have.
More importantly, through those and varied agency 870s over the decades, I've shot at least 50K rounds and maybe twice that.
I wasn't counting.
I instructed, shot demos, qualified, competed, (HOA at a couple 3 gun meets), hunted and even shot rats at the dump.
Yes,I'm good, though far from perfect. And I got that way by shooting lots of ammo in lots of ways at lots of things.
Don't get me wrong. If all that stuff helps you direct the shot and/or improves comfort while so doing, more power to it.
But the first thing anyone should buy for a new gun of any type is ammo.
Lots of it.
Then, you have a better idea of what your shotgun needs and what's just bling....
