I didn't mean ammunition was not available (although future supply as compared to the popular cartridges is still a question), just that it requires a certain dedication to sourcing, paying more than 9mm, stocking and/or setting up for reloading a cartridge that's only used in one firearm.
The guy who bought one at $189 because, hey gun under two hundred bucks why not, he gets tired of going down to Wally's Sporting Goods and paying a dollar per round (yes cheaper from site sponsors). That's the gun that ends up getting sold, and I doubt he's expecting $600!
