These are tough times to introduce a new handgun cartridge. It's tough for buyers to spend the money, it's tough for businesses to have a lot of capital tied up in inventory that doesn't move quickly.

One has to look at the spectrum of cartridges available and honestly ask, does a new round fill a real gap among existing rounds, or is it primarily something to generate extra demand?

I hate to see it go, but the market will determine success or failure. Even if there are no new guns made (which I doubt will be the case), the ammunition will be manufactured occasionally for a really long time, it will just be harder to find and more expensive.
