Is there anything on the web I can use to look up serial numbers that will identify the gun Any help appreciated. I just want to know if this gun can handle 3 loads if I get different barrels for it or if the gun itself is actually chambered at 2 34. Is the gun actually chambered at 2 34 or is it just the barrels The new 870 Express looks to be chambered at 3 according to Remingtons website. Im guessing its not a magnum since it doesnt say magnum anywhere. It came with 2 barrels and both says something to the effect of Can use 3 and 2 34 loads in magnum models. On the gun, it simply says Remington 870 Express and on the box it says its the Remington 870 Express Combo. Neither say magnum on them, yet both show the serial number ending in M.

If I recall correctly the SN prefix letter started in the mid-1960s. The Collectors webpage also had a rough date range for 870 receivers based on the prefix letter. I also tracked the manufacture years of my two Wingmasters and an 870 Special Purpose by calling. He checked some other records and finally came back with 1960. She had to consult the custom shop and the custom shop guy asked me some questions about the gun. I sort of stumped her one day when I called in the SN of the 870 TC I bought about 8 years ago. Plus, when Remington was in business you could call and get routed to a very pleasant person who would look up the manufacture year of your receiver. The Remington Collectors website has the code key, it’s also on this website in a couple of posts.
