The biggest I've ever carried concealed is a 7.5" Ruger Super Blackhawk in an Uncle Mike's Sidekick holster with its own Sidekick belt. I carried it crossdraw under an oversized hunting jacket last year when we were cruising the woods during the deer season. Several times I'd forget that I had it on when we stopped into a rural diner for lunch.
Of course, being in the rural deep South, if anyone noticed it, they'd likely not say a thing.
