870 Express MIM extractor - ever seen one fail?
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?
