Let me start by saying it is because of hickok45 ( youtube channel) that I decided on this shotgun. I chose buds because they sponsor him and for the price. 100 lower then my local shops could do, even after tax and FFL transfer. I am impressed with how easy it was to buy from buds. Ordered on a Saturday received on Friday. OK, about the 500sp. Product was free of any imperfections or scratches on the finish. I shot 100 bird shot, 15 1 ounce deer slugs and 15 3 inch magnum 00 buckshot. No issues with this 500sp at all. I would recommend mossberg to anyone. Great home defense option.

Great product, I couldn't be happier. Lots of factory grease as expected just a little cleaning gets rid of it. Shoots flawlessly, put around 75 rounds through it already and no hiccups.
Buds is always great
