I've been using a Mossberg 500 turkey gun for years.
I selected it not because of any love for Mossbergs, but because the safety was located where I prefer them.
My opinion of the Mossberg 500 is that it's not very pretty or fancy, but it's like the Energizer Bunny- it just keeps going and going
Never had a lick of trouble with it, and it's always performed well.
There are also a bazillion aftermarket toys for the Mossberg 500.
I also know the miltary has used a bunch of Mossberg 500's. fwiw.
