Stumbled across some interesting ammo online that got me to thinking about 5.7x28 in handguns.
We all know the primary claimed advantage of 5.7x28 is its velocity - approaches, sometimes exceeds 2K fps from a pistol. And it isn't magic, it just shoots light small projectiles.
Well, what if you had 9x19 or .357 SIG defensive HP ammo that had even more velocity and more projectile mass (than the 5.7x28) and you could use it in a Glock 19/17, or a SIG 229/226, or some other standard 9x19 or .357 SIG pistol??
And because of the velocity, it shot flatter than standard 9mm ammo (another of the claimed advantages of 5.7x28)
https://libertyammo.com/product/civil-defense-9mm/ - 2KFPS and independent tests (even by Paul Harrell -
) show that it not only meets that velocity, but often exceeds it.
The .357 SIG 50 gr ammo claimed velocity is 2300 fps.
So there you are, if you think the 5.7x28 is something special, then so is this 9x19 & .357 SIG ammo, plus the latter has the advantage of a much wider selection of guns that shoot it, and if the Liberty ammo isn't available, you can fall back to much more available conventional ammo.
Please bear in mind, I am not poo pooing the 5.7x28; I have three Five Sevens and three PS90s as the first line of defense for my family if SHTF. I am just saying that if ultra light/fast projectiles in handguns are good, or they fill some niche for you, then you don't necessarily have to go to the 5.7x28. However, the Liberty ammo is about twice as expensive as 5.7x28 ammo.
