I’ve put a couple thousand rounds through mine and been extremely happy.
Below is the link to a podcast put on by primary and secondary in regards to eroding gun rights. It’s number 136 in their series.

New 870's are hit or miss. Older 870's are just fine. Recently took a shotgun class where the only gun that had an issue was a brand new 870 tactical. It wouldn't extract certain bird shot. The mavericks, 590's and 1301s in class all ran fine.
