You can bet that some minor volume ammunition will be sold and will not be replaced soon. If an ammunition company has already sold more than 9 mm ammunition than they had in stock, do you think that their machines will be restarted and restarted to make a lot of .357 SIG mum, for example? It is not likely. Once the current offer of .357 GIS is exhausted, it will be a while before the ammunition manufacturers have breathing room to start making loads that are less on demand.
