I have an older 870 12g from 1991. It has the metal trigger group and the police extractor. I bought it used, so I will assume it may or may not be stock. I ordered a couple more extractors from a major online retailer. One of the extractors I ordered looked just like the one on my 1991 870. The other looked slightly different. You can see the difference when the parts are installed. The slightly different one looks like they skipped a bit of machining. I don't have a way of posting a picture at this time, but the machining that is missing on the one appears to smoothen out the angles of the extractor so it doesn't hit the reciever when the pump is operated. More of a rounded appearence when viewing the portion of the extractor that you can see when it is installed. Hope this makes sense. If not, I will work with my wife on trying to photograph it. Did they change the design of the non-mim extractor? Thanks, Jon Wanna kill these ads? We can help!
