Default Quick question about 870 Police

Are all Remington 870 Police models able to shoot 3" magnums? I'm asking for a friend. I found his dream setup with rifle sights, wood stock, and extended tube. Thank you for your time and consideration.

It should be on the barrel. There are quite a few older guns out there that only have 2 3/4 inch chamber's.

No, check the serial numbers to be sure. Magnum guns will usually be stamped “Magnum” or have an “M” at the end of the serial number.

Remington recently ran out of "M" serial numbers. The new Pmax 870s end in X I believe.

All 870 police shotguns are “magnum” receivers. But you must look at the barrrel. It might be an aftermarket barrel of 2 3/4” instead of a 3” chamber. If the receiver says 870P or the serial number ends in “M”, you’re good. Part 2 however is to verify the chamber size on the barrel itself. If it doesn’t say “3” or “3 inch magnum,” you can only safely shoot 2 3/4”.

I have an 870 Police Magnum with a regular bead sight and it says 2 3/4" or 3". Best bet is to check the barrel.
