The FN-designed 5.7x28mm caliber has joined the ranks of 5.56 and 7.62 by recently being standardized by NATO.

Looks like more firearm manufacturers will be producing 5.7mm?
I wonder will the price of ammo come down?

I haven't read much about the 5.7. Haven't been interested in it due to ammo costs. But yes, with NATO adopting it, there will be ammo manufacturers around the world cranking up production of that caliber. A major increase in supply, especially for imports from countries with lower labor costs, should lower prices significantly and likely increase load choices.

If it penetrates body armor, it won't be available to the public.
There are rifle rounds available to the public that will penetrate Type III armor.

Correct:
I read, that specific round (penetrates body armor) only the military and law enforcement will be allowed to get that type of ammo.
WE civilians will get the civilian market ammo.
As far as reloaders, maybe they could?

A background article on the cartridge:


It specifically mentions the FN P90 PDW in use by many nations.

It goes to show you, they new they had a issue with body armour in the 1980's and in 1990's made the 5.7mm.
The 5.7 has been evolving every since and will continue to evolve.
Now with NATO adopting the 5.7mm it should increase market share and with that more firearms for all of us?

NATO Standards (STANAGS) don’t “do” anything except set the specifications. It in no way guarantees that any NATO country or organization is going to procure any weapons in that caliber. For any that so, however, the STANAG ensures interoperability.

I wouldn’t be running out and buying stock in 5.7x28 manufacturing companies…

The first picture shows a date of March 2021; is this a new development?
No its old news reported on fnforum.net long time ago. FN still controls most of the brass and their proprietary coating required to make the FsN pistol/PS90 cycle properly. There is a lot more info on this on the FN forum. Ammo acquisition is still an issue, especially self-defense ammo (unobtanium except small single box quantities), The SS197SR polymer tip in the OP image is considered range practice ammo by a 5.7x28 US joint agency study not suitable as a duty round. Speer has started to ship production but small quantities.
