Federal Premium Personal Defense HST 9mm Jacketed Hollow Point

A: Hi Brandon, They're exactly the same it's just now the newest P9HST2S claims to be for "Self Defense and Personal Protection" and not just "Personal Protection" So they branded it with a "S" Also the P9HST2 is 50 rounds while the is 20 rounds.

A: same ammo different packaging they are both 147 grain HST ammo

A: Brandon, the only difference is that P9HST2 boxes are marked "Law Enforcement" and the P9HST2S boxes are marked "Personal Defense". The ammunition is the same exact specifications between the two. You can save a few cents per round when you can find the 50rd boxes.

A: HST2S uses 147 grain bullets while HST1S uses 124 grain bullets. The heavier bullets have slightly lower velocity and overall muzzle energy and slightly lower recoil as well.

A: The difference is the weight of the bullets. The heavier the round loses velocity slightly. HST2S-147 grain HST1S-124 grain

A: Hi Yitzhak and welcome. The weight of the projectile/bullet on the HST2s is 147 grains and the HST1S is 124 grains. The 124gr bullet will be faster and expand more but penetrate less and the 147 will be slower, expand less and penetrate deeper. Both are excellent self-defense rounds. Carry lighter in the summer and heavier in the winter due to light and heavy clothing. Cheers and stay safe!

A: Yitzhak, the HST2S is 147 grain ammo, and HST1S is 124 grain ammo. Stay safe & have a great day!
