I own a 930 that just runs and like it. Two of my shooting friends also own 930s, and I know one of them even Mossberg couldn't get to work after multiple attempts.
Not great odds.
I don't know anything about the 11-87P; I stick to the recoil operated 11s and 11-48s, but I ran into this one while wandering around GB the other day, and it's right at your price point. https://www.gunbroker.com/item/782967620 Malkoff makes a conversion for the forend. Anyone have any experience with this model?
I don't pretend to be a shotgun expert.
That said, waaay back in the day when I shot a lot (90s) practically everyone (generally GMs and master class types) in my part of the USPSA world had the same thing to say "If you have questions about shotguns, talk to Pat aka Mr. Auto-5". The primary Belgian Browning that I use today as a house gun came from him, and it may not be state of the art by modern standards, but it runs like a champ. Plus (Not really relevant but still cool to me) A5s cycle really, really fast!
That was a long winded way of saying that I would pay very close attention to what Pat Kelley has to say when it comes to shotguns. He is a true subject matter expert, to put it mildly.
Cheers!
