Curious what year did Remington come out with the "magnum" receivers to accomodate both 2 3/4 and 3in shells?

According to this link (http://www.remingtonsociety.com/rsa/journals/870/?na=5) from the Remington Society of America, the 870 Magnum was introduced in 1955.

Are express magnums the only 870s that can shoot 3"??

My 870 Police Magnum will also shoot 3"

No...If there is a "M" in the serial # then its a Mag reciever....CKECK the Barrel for 3" also, as some people have switched barrels and you can easily find Mag recievers with 2 3/4" barrels on them.

Most 870 models came in the 3" opption

^^^ Good stuff ^^^

If memory serves every 870 receiver regardless of sub model since the introduction of the Express has been a magnum length, but they are not always rollmarked with 'Magnum" in the branding on the left side. The "M" at the end of the serial number is the proof positive that you have a magnum receiver. Barrels come and go, so as Thefeeder says, always check the markings on the barrel for chamber length.

Ok makes sense I did see a "M" on the barrel of my 870 but just wondered if the magnums were the only ones that shot 3". Figured that's what the M would mean using my awesome detective skills lol
