And you're going to buy this ammo where-in lots of 100,000 rounds or better? At a price that fits within the budget? If no one wants to supply ammo in the quantities necessary for training and practice at a price you can afford, the round is useless. We were able to keep it in service as long as we did by long term contracts orignially piggy-backed on federal contracts for millions of rounds. When they ceased, so did the manufacturers interest.

Bluntly, we originally adopted the 10mm for exactly the same reasons as the FBI/Virginia State Police: politics. Also the my gun/ammo is bigger than yours feeling that the guys making the decision got.

Whatever advantage you may feel the 10mm might have is negated when you can't train sufficiently to properly utilize the weapons system. Much better to have a caliber/weapons system that the troops can extensively train with.
