I have had them all at one time, but still have the Win mod 12 20ga, Moss 500 12ga& Moss 835 12ga..

I've shot both and the Remington 870 Express just feels more solid to me.

I have a black Remington 870 Express Super Magnum. I paid something like $280 for it. I wanted it to get started in duck hunting. I didn't want a pretty wood stocked shotgun because I knew I would freak out if I got it wet or muddy or the other hazards of duck hunting. The gun has done exactly what I have wanted it to do, very reliably. It has never malfunctioned. What more can you ask of a shotgun? I suppose the Mossburg may perform just as well in this regard, but I'm satisfied with the 870. I've used it three seasons now.

Mossberg, I wont buy another remington in anything. POS 870 in matt finish rusted within the first month, damn thing jamed too. It made a good anchor. Mossberg is the better gun. I just bought my son one today, a youth 20 pump. Smoother than the Rem. Made in the USA, man mossberg has some nice gun out now. Lots of deer rifles too. Nice ones too.

Link to some quality remingtons. Buwahahah.

870. the action is slicker as less parts.i have 3 of them. i don't like the bps. i have one in .410.

Neither is the wrong choice. If you know someone that has either one, or both, try them out. Buy the one you can hit with the best. Shotguns are like that. Fit is really important.

I have the 500, never a hiccup.

i have had two 500s one i bought used one new.
They where both top grade guns infact i looked at the rem and most other pumps and figured why not just buy the 500. In my book the best shotgun ever made

I have an 870 Wingmaster made in 68 and a 500 made in 88. Absolutely no comparison... The word Yugo is coming to mind again OEH throwing the Mod 12 in there is throwing crap in the game...those were some sweet guns!

Still have mine that was my dad's....

I have to go with the Rem 870. Not that its any better than the Mossberg. But like you, its what I cut my teeth on and it just feels right. I have 2 20s and 1 12 in the 870.
My friend has a Win Model 12 and a Mossberg 500 and they just do not feel right to me. Again, not saying they are bad. Lord knows the model 12 has a great reputation in the field and on the trap line and the Mossberg is a working man's gun. But again, so is the 870.
