I have had a Mossberg 500 for about 5 years, no major issues and i haven't been gentle with it. I love it.
This year I decided to see what all the hype was about the 870 express. First round of skeet, stove pipe. Second round, spent shell and new shell jam in receiver. Third round, stovepipe. Fourth round, stovepipe....... This is the heaviest, worst gun I have ever used.
Speaking with another customer at gun store about his 870, he tells me how great it is. All he had to so was install over sized safety, polish the chamber so it would stovepipe less. He said the only issue is it doesn't extract and tears the rim of the shell, oh and it only likes certain shells. I look at him like he has 3 heads and say "my Mossberg didn't have any of those issues.
Not liking the 870 I got an SXP. I love this gun, shoulders and points like a dream, hit what I point at. Only issue so far is the finish. The black on the receiver scratches easy, loading shells the rim of one brushed against the receiver and scratched it.
I loved the SXP Field so much I didn't want to bring it duck hunting in the marsh or drill the nice wood for swivel mounts, so I got the SXP Waterfowler.
The waterfowler is heavier and doesn't point as well as the field, for me at least. I bought it last Friday ro use Saturday for the duck opener. Used it for 3 hunts and went to clean it Sunday night only to find the camo finish peeling badly. It was clearly not appled properly. I'll try and post pics later.
My experience dealing with Mossberg for minor issues has been great and hassle free (no swivel studs for 3 barrels and a broken fiber optic sight i broke dropping the gun) looking forward to the last 5 years of my 10 year warranty.
Dealing with Winchester and Remington is a nightmare. Well I can't say that, Remington won't even reply. Winchester has given me the runaround and is not reaponding to my emailed pictures requesting this be covered by Warranty. The best was Winchester Canada's answer "well It's going to peel eventually" to which I replied "my 5yr Mossberg 500 in camo isn't peeling yet"
So in conclusion, stay far away from the 870. A friend offered to buy mine but I wouldn't sell it to a friend, It's that bad. I didn't even touch on the other issues, I will be posting a review of all 3 in detail once hunting season is over.
The SXP is nice, especially the Field model. the finish on both is bad, the waterfowler is terrible. The customer service is terrible, unacceptable.
The Mossberg 500 is my go to dependable shotty. I actually brought it as back up last weekend. Only issue with it is the rattling of the fore grip, my only complaint. Everything is better, right down to safety and action release location, your hand doesn't leave it's natural shooting position to work both. The SXP is a close second with its safety in the front. The 870 you have to release the grip to release the action lock and safety is behind the trigger.
Get a 500 or a SXP Field, speaking from experience and not hype and history. Remington is not what it used to be.
EDIT: To be fair, I have to say the action on the 870 is very nice. I just got home and was palying with it and want this thing to work, I'll keep at it.
