We'll know for sure when the January data for FBI NICS finalizes. In normal times January sales plummet from December peaks. If January numbers are as high as I suspect, near November numbers of ~2M, then the whole supply chain will be empty until July regardless of the politics.
Due to the crazy sales this December, then I suspect the January sales would have to be below January normal for the supply chain to even begin to catch up. Normal would be ~1.5M.
For the first 2 weeks, from 12/31/2012 to 1/13/2013, the NICS has been completed ~1.1M times. So ~1.5M will be easily beat. I suspect the month will hit around ~2.2M +/-10%. This makes me conclude that supply chain and prices won't stabilize until very late in the year, maybe July or August.
