If S&W could sell a 10mm in the Shield 45 platform or a 45ACP-10MM conversion then I think the 10MM would finally take off as a mainstream round. It already has a nice following in several full sized platforms. Colt Delta, Springfield TRP Operator, Sig, several others. I really don't see any other calibers out there other than the 45 for serious military applications. Who cares if the FBI agents who tried to qualify couldn't control their weapons. I think it is only a matter of time before it is accepted by the military as an issued sidearm for at least one of our branches of our military. When that happens we can be assured ammo will always be available and when that happens, people buy that caliber.
