I've had my 870 for a little while and although it was a good gun, I never quite adjusted to it. As a lefty, I found the stock would do a number on my face and the safety wasn't the best for me. Been thinking about a Mossberg 930 for a while and went to look at some Saturday, ended up coming home with a Mossberg 500 after all was said and done, the 930 just didn't fit right, the 500 popped right in place and the bead was on target immediately.
I got the Field & Defense combo at Cabelas which replaced what i had in the 870.
So far I really like it and all the functions feel natural, I field stripped it, wiped everything down with CLP and put it back together - all that's left is to shoot it!
I think I'll keep it loaded with Federal 00 Buck with Flight Control wads, but do have the Winchester PDX1 loads for it too, we'll see.
Here it is with the 20" breech barrel, it also came with a 28" ribbed and ported barrel with center bead.
