It would be safe. BUT you may experience ejection issues. I said MAY because some 23/4" receivers will eject 3" cartridges.

If you experience ejection issues a smith will have to install a 3" ejector. Polishing the bore will cure extraction issues. In any case no damage will occur to you or your gun.

Yes it is. 3" receivers (early) will be marked magnum. Non 3" will have a "V" in the serial #. I have never seen a non magnum receiver eject fired 3" cartridges but I have been told some will. I recommend a 3" magnum receiver be used with 3 " cartridges as a best practise.

Mine does. It has the V in the serial #, not marked magnum. Hasnt ever given me an issue ejecting 3" shells.
That said, if you're doing this BE SURE THE BARREL/CHAMBER IS MARKED 3"
The difference between a magnum receiver and a regular receiver is the position of the ejector pin.

While some receivers eject a 3" shell just fine, you can actually modify a 2-3/4" receiver to eject a 3" shell by moving the ejector back. There is a small amount of smithing involved.

What if you have a receiver marked 2 /34 and 3 inch... and replace the barrel with one marked only 2 3/4? Is it the receiver that determines the shell length capabilities? or the barrel as well?
If the barrel is only chambered for 2-3/4" shells you could have a 3-1/2" receiver and it would still only be safe to use 2-3/4" shells. In the case of the 870, the ejection port happens to be long enough to eject 3" shells most of the time (YMMMV). This isn't something that applies to all guns. Always follow the data stamp on the barrel with regard to shell length.

Its the barrel, as that is where the chamber is located.
The only negative outcome of shooting a 3" shell from a 3" marked barrel on a 2 3/4" receiver is it might not eject properly. I have a 2 3/4" receiver and a 3" barrel that happens to eject 3" shells fine.
I actually emailed Remington on this a couple years ago.
Heres the chain of emails
Would love to find one of these they talk about and yes they told me the same at one time when I asked. They don't exist but they keep on saying it
I have measured guns from the 50's and up and the only one with a longer port is the 3 1/2" super mag
Every other receiver has been the same other than the 3" ejector being fitted
Personally I think they are getting 1100's and 870 mixed up
There is no size difference in a 870 mag or V that I could ever find and have seen many V guns handle 3" with just a barrel change since some where in production that no one knows remington started fitting 3" ejectors in all 870's but we have no dates or serial numbers

That one is not possible
Crap.....I was misinformed then.
I was told that repositioning the ejector and enlarging the port was all it took.
That is a start then the bolt is different and the trigger pack and lifter are different. The barrel is also obviously different - able to chamber everything up to the 3 1/2-inch shells.
The receiver is definately heavier also although some say no
If I am wrong someone please chime in and correct this since I only have two of these 3 1/2 (if you add the wingmaster 3 but she has never been apart)
and don't play with them in pieces comparing items like I do with other 870's.
Cheers

The slide arm assembly also has some slight differences in dimensions to allow about 1/8" more reward travel. As for the receivers, besides the larger port opening and ejector rivet placement, I can't find any other differences on them with Super Magnum being about 3/4 oz. lighter due to the larger ejection port. Standard, Magnum and Super Magnum...they all have the same profile and measure 1.40" (+/-0.005") in thickness at both ends The new Wingmaster (1992-current) and Wingmaster Super Magnum (2000-2008???) are about 1/4 lbs lighter than the Express versions because of the "Light Contour" barrels.
