The only downsides that I can see are that the finish doesn't lend itself to concealability in the dark,

I can see that that might be a problem in certain circumstances.

and I've read that the bead is plated at the same time as the barrel and action, so you'd need to crack the nickel if you wanted to put different sights on it.

That, too, could be a problem if that was your goal. I have never re-sighted a shotgun, so it's just not a problem for me.

I'd want to put tritium ghost ring sights on it if/when I make the purchase. That's the main reason I brought up the latter point. If the break in the nickel can't be seen, I think that'd just about nullify the problem for me.
