Also the extractor replacement on the 870 is a weld job.

The
extractor on an 870 is easily replaced with a small screwdriver, a few choice words, and some patience. The
ejector, which is what you're referring to, does
not require welding to replace, but it does require some special tools...and usually refinishing the receiver as well. Frankly, I don't see why it matters that much. I have 870's from the 1950's that have never been refinished and the ejectors are just fine. There are probably close to a dozen 870
wingmasters owned by my immediate family and myself. Never once has any of them had an ejector failure in thousands and thousands of rounds. On the other hand, we have all had mossberg 500's fail in exactly the same way---failure to chamber the next round, instead dropping it straight out the loading port on the bottom. I have seen 870 express models so poorly fitted from the factory that the trigger group pins would fall out if the gun was tipped to the side.
