Am I fretting too much over the 870 ejector (which seems to be my biggest hangup)? Also, I know the 590A1 is a military shotgun, but will the alloy receiver stand the test of time? I also appreciate the steel receiver of the 870 over the alloy of the Mossberg.

I believe my mind is set on the 590A1, but I don't mind the Remington and I have just a tad more time on the 870, maintenance wise. 6) from an armorer perspective, the area where the action bar lock contacts the action bar seems more robust on the Mossberg. I have seen 870s with loose latches and while the fire control group pins can generally hold them in place, they can skip and cause feed issues. 5) The shell stop latches are removable where as they are staked in on the 870. This only seems to be a problem with the 870 when wearing gloves. 4) The shell lifter retracts into the receiver so there is no "loading gate" in the way when feeding shells into the mag tube. 3) Dual extractors for redundancy and reliability, although I don't really hear a lot about 870 extractors breaking. 2) The ejector is screwed in and is easily replaced, whereas the 870 ejector is riveted in and is a PITA to replace. However, tales of the plastic safety breaking are all too common and you never really hear of the 870 safety having problems.


1) Tang mounted safety is truly ambidextrous and is only a hindrance with a pistol grip, which I don't plan to use. My current defensive Shotgun is a Benelli Supernova Tactical, but it just doesn't fit me well.Īfter doing my own research and going through armorer school a couple of times, I've come to appreciate the Mossberg design over the Remington.

I have about equal time on shooting both systems, having used the Mossberg 500 platform in the Army and the Remington 870 platform at my agency and for hunting and clays. I am the Shotgun Armorer for my agency and I'm certified in both Remington and Mossberg platforms, though I have more time on Remingtons because that's what we have at work. I am in the market for a new pump-action 12ga shotgun and have narrowed down to the Mossberg 590A1 or Remington 870 Police Magnum. I did use the search function first, but didn't get the answers I wanted. Longtime lurker on the site, but first post.
