While supersonic is a superior all around personal defense round, I should point out that I’m not carrying it either! All 9mm from Fenix is subsonic 😁

I’m all twisted up I guess… lol 😂

I guess my round is indeed considered supersonic.

Yours being a heavier grain would be most likely considered subsonic.

The sound barrier where I live is slightly less than 1100fps, and this ammo I carry is metered right around 950

1125 fps where I live for the most part depending on temperature and my rounds are 1135 fps. 👍

My range rounds are 1125 fps so right at the border.
