Description
Federal’s HST load was developed for law enforcement duty use, which tells you a great deal about what it was designed to do: function reliably under pressure, expand consistently after passing through intermediate barriers, and retain enough mass to achieve meaningful penetration without going further than necessary. Those same properties translate directly to civilian personal defense applications.
The hollow point cavity is engineered to resist plugging when the bullet passes through heavy clothing, drywall, or other common barriers before reaching the target. That matters in real defensive situations, where the bullet rarely travels through open air alone. When it does expand, the jacket and lead core are designed to stay together rather than fragment, keeping nearly all the original bullet weight working as a single unit through the wound channel.
The 125-grain projectile exits a 4-inch test barrel at 1,360 feet per second, placing it in a useful range for the .357 SIG cartridge — enough velocity to drive reliable expansion without pushing recoil to a level that complicates fast follow-up shots. The nickel-plated case aids feeding reliability and makes it easier to visually confirm a chambered round, while also resisting moisture better than bare brass during long-term storage in a carry firearm.
This load meets the FBI test protocol that agencies use when selecting duty ammunition, covering penetration depth, expansion diameter, and weight retention across multiple barrier scenarios. For anyone carrying a .357 SIG pistol and wanting a round vetted to the same standard as law enforcement duty ammunition, this is a straightforward choice. Available in 20-round boxes and 200-round cases.
