    The only .380 ammo that functions as desired/required. HST is used for all my pistol self defense needs.

    I use this in my (somewhat ammo finicky) Seecamp for EDC. I have never had a miss-fire, FTF, stovepipe, etc. after 200+ rounds fired so far. It does not tumble or keyhole, unlike other JHP ammo used in my Seecamp .380.

    With a little over 300 rounds of this through my LCP II I've yet to have a misfire, FTF, or any other issue. Every round has fired as expected. Recoil is a little snappy but that's to be expected in a gun like this. I would and do trust my life to this ammo.

    Works perfectly in my P380 and my wife's M&P Shield EZ. HST rounds are what I use in all my carry/home defense pistols!

    Feeds flawlessly through my LC380. My first choice in carry ammo. HST is my first choice in 9 mm and .40 S&W, as well.

    These .380 HST rounds have been flawless through both my Kahr P380 and my Scott McDougall Colt Pony Pocketlite. Very manageable recoil. The ballistic gel tests speak for themselves.

    I switched from Hornady critical defense to the federal hst. These seem to be a great self defense round for the .380.
