I noticed LG Outdoors and Wholesale Hunter suddenly have the 1851 .36 sheriff back in stock (8 of them). On Gunbroker and their website too. I don't feel comfortable posting links.
I think those two stores are more or less the same retailer. Because 2 weeks ago they both had 2. Then they both had 0. Now they both have 8. Maybe found in their back room or something.
EMF is still sold out, and everywhere else I checked still sold out.
