Ill add to this since I was asked to review this shotgun as well. I am going to write it as if I never read yours or saw your post:
To start off out of the box this was covered in heavy oil. Even under the oil my brushed nickel finish looked great and the jewled bolt really stood out. Once wiped off the first thing I noticed was how smooth the slide runs. It might as well be rolling on ball bearings.
Upon further inspection, you can tell this is an inexpensive shotgun with some quality issues labed in pictures below. Machining marks and nicks on the receiver. A little overmould with the stock. Honestly nothing worth complaining about, but worth a mention.
With out an initial internal cleaning (I was too excited to clean it first) I took it out and shot Winchester bulk though it, and Winchester deer slugs. Performed famously even with known bulk pack issues that I will have in my Mossberg. Not even a hint of trouble.
I picked my gun up for 230 dollars, plus shipping, plus tax and FFL fees through my dealer. I am about 300 dollars into this shotgun, and very happy with it. The extra shell holder is a nice touch, even though its not a HD gun or a hunting gun. However with that being said, I feel very confident and would have no problem making this my home defense gun.
Here you can see the nick at the top of the receiver, from the factory
You can see on the ejection port this is not a clean, nice straight edge. Im not complaining but its worth a mention. Its a machined receiver, I do not know why its not a nice endge
More semi rough edges
Machine marks on the inside of the receiver
Machine marks on the outside of the receiver
This is what I was talking about the overmould in the stock. Its not bad, but the edges are rough and a little high. Not on the same plane as the receiver. I dont personally care but being as this is still a review I will make mention of it. Its nothing you notice when shooting, just under careful inspection
Lastly, in the cold and with my bare hands, this grip is awfully sharp! I am going to knock the edges off a little because it really leaves a mark and gets uncomfortable rather quick when plinking (AKA putting lots of shots down range)
And here is a quick little video I made of how smooth the action is on this gun. You click the slide release by the trigger and it just falls. Its fantastic
In conclusion, its a well built, most likely durable, fun to shoot, reliable (so far) good looking shotgun. I already want another I like it so much. The action is smoother than any Mossberg or Remington I have ever shot. I have not handled anything nicer. However I did have some small finish issues here and there. Nothing I personally worry about, nor should anyone else who buys a 200 dollar shotgun. For what it is I think its fantastic.
