Old_Writer... thanks for that list. I've not followed closely recent developments in adoption of the 5.7mm cartridge but will do so. I will be happy to learn it if they've found a new bullet(s) that have overcome the glaring deficiencies of the round in previous testing and experience.
Of the agencies you've listed, it will be interesting to see which ones have adopted the 5.7 as a submachinegun round and which as a pistol round. For instance, I am aware that the U.S. Secret Service has had 5.7mm SMG's for a number of years, but the standard round for pistols is NOT 5.7 as of my last contact. I'll be looking into this further. Thanks for the list.
Your comment about ordnance people here in the US being pleased with the 5.7 intrigues me. I've got some calls out and will be looking into this as well.
Could you do me the favor of citing a source for these favorable reports by ordnance people? I'd like to read them. These were NATO ordnance boards, not US military boards, I presume?
Finally, I'm intrigued by your reference to a common round for pistol and rifle. This concept has always puzzled me, as the experience of our military, and that of a number of other countries around the world, has been that a common pistol-rifle round is a compromise that satisfies the requirements of neither, but I'm open to the discussion.
