is the remington 887 nitro express tactical worth the money?

Now, i already own a mossberg 500 field gun that i put a 18.5" barrel onto in place of the 28" vent rib it came with. Now, im not a hunter, and am really just a firearms enthusiest who enjoys fun/target shooting, and values the role they play in equalization against a threat to my life or home.

Ive heard they have been having issues with them, like rust under the polymer Armorlokt outer shell that is supposed to keep out the elements near perfectly, that they have had issues with the bolts coming out of battery when fireing the powerfull 3 1/2" shells but some people say through experience thats just from not haveing a grip far enough back to avoid pulling the slide when the gun discharges. Etc.. so my questions are what r ur personal preferences/opinions on this gun, im gonna be going to pt firearms tomarrow to take a look and see if they have some, and if not check out their prices on the mossber 590's their just cause thats my backup plan.

I also need a slightly less weighty gun than my mossberg (which means the remington will be about a pound less i beleive but thats not my primary reason and really doesnt matter) anywhoo, id prefer not to here about how i dont need a gun if i dont hunt or any other bull like that as its my constitutional right and if i want to own a shotgun for self defense or just to shoot on a beautiful day outside than imma buy a gun. Thanks.
