Firepower, I don't know the availability these of shotguns in PK but I would recommend a Mossberg 590A1 or a Remington 870 (Police magnum if available).
The Maverick is the "poor man's" pump shotgun. It works, yes. There are others with better fit and finish for a little more money, yes.
I personally don't like the rattle of the slide on the Maverick. If I am trying to move quietly in the woods or through my home I don't need the gun to make extra noise.
