I have been shooting my 870 Express for a year now. Everyone says to upgrade the extractor to the milled version. The logic is that it is cheap insurance. I would be interested to know if anyone has first hand experience seeing a MIM extractor fail?

Bonus question - people also say to upgrade the carrier dog follower spring. The idea is that the heavier duty one makes the gun more reliable. Has anyone ever had a feeding failure due to the standard express follower spring?
 
I have one i picked up used years ago. It has been my brush/truck gun. It has seen well to put it nicely, hard service. A couple years after I got it the ejector spring broke out while shooting a round of sporting clays. Dug it out and kept going. Never did take the time to replace it but that has been the only problem with it. Works like a champ, nice and smooth action for $200. Eats everything i put in it from the lightest field loads to the 3" 1 1/4 oz magnum slugs.

Nope, I have never seen an 870 Express stock MIM extractor fail, and issues relating to the carrier dog follower spring are rare. However, I always upgrade both because the cost and time involved in doing so are minimal (the spring costs about $4 and the extractor about $12). Interestingly, Remington charges the same for either carrier dog follower spring, so you have to wonder why they just don't use the heavier spring (used in the Police) in the Express. The answer, of course, is marketing. BTW, I also always upgrade the magazine spring to a heavy-duty Wolff spring ($8.99).
 
I've had issues related to the carrier dog follower spring. Replaced it, and all is well again.
 
I just ordered the heavier duty dog carrier springs for my 870s. I think I will keep the MIM extractor for now.
 
I have never seen one fail, and I know a LOT of 870 shooters with a LOT of rounds through them. (hundreds of thousands of cumulative rounds)
 
MIM is cheaper production, but MIM makes for stronger parts. google it lots of info about MIM production out there. purist's dont seem to like MIM.
