What exactly makes a shotgun a magnum, the receiver or the barrel. I'm working on the purchase of a Remington 870. The receiver only says Remington 870 but the barrel says 2 3/4 and 3in. Is this an express or a magnum or is it both?

Calling aippi....

I think that a "Magnum" 870 has both a different barrel AND receiver, but I could be wrong.

I'm pretty sure all the 870 receivers are the same, and they'll all handle 3" out of the appropriate barrel.

They are not all the same. The receivers that handle the 3" shells have a different ejector. However, you probably have to get a receiver that is 20 years old or more to find one that does not handle the 3" shell. Well, it will handle it, it may just not eject it....

Back when this was a common issue, the "magnum" receiver serial number would end with an M. Not sure if they still follow that or not, since you will find that most shotguns on the market today will handle a 3" shell.

And of course, you need the appropriate barrel as well.

Mine is a new 870 and it ends in "M". It's up to 3".

As stated above, there are 2 3/4" Wingmaster receivers out there but all modren 870 are 3" receivers unless designated "super magnum" then they handle up to 3.5" shells.

As for the word magnum having anything to do with the size of the shell or ejection, it does not. Our Departmental load was 2 3/4" magnum ( 12 pellet) 00 buck for many years.

Magnum simply means more lead and more powder and can be 2 3/4", 3" or 3.5". The chambering and the ability of the receiver to eject the spent shell is the issue.

The weapon you are looking at will handle up to 3" shells and yes, that can be the 3" magnum loads if that is what you want to shoot.

Thanks all for the replies, I've got a couple of guns in small shops locally that I'm watching so I'm sure within the next few days I will be picking up an 870.

I went kinda overboard saying they were all the same, I was totally forgetting the 3.5" guns, and the older short receivers. Aren't the Special Field receivers proprietary to the model too?

Well, without starting a new thread, I found a starter gun for my tactical build, online. The more I read the more I think I'll be keeping this sort of basic. I have added a sling and have a mag extension on order but for now I think the only thing I'll be adding is a bracket to hold a TR1 light that I already have. Here is a picture of the basic gun.
