Hornady Subsonic .40 S&W 180 gr XTP Ammunition

Description

If you're running a .40 S&W that's threaded for a suppressor or just want tamer noise at the range, this is the load to grab. Hornady engineered this subsonic round to stay below the sound barrier at 950 fps while still delivering meaningful energy—361 ft-lbs at the muzzle. That's no slouch, especially when the bullet does its job on target.

What Makes Hornady Subsonic Stand Out

The 180-grain XTP hollow point is the real heart of this cartridge. It features Hornady's signature design with six serrations that weaken the jacket just right, allowing the bullet to expand reliably even at subsonic speeds. The flat profile and patented Flex Tip insert help ensure consistent expansion without the unreliability you'd get from normal hollow points running slow. This bullet has earned its reputation for controlled, predictable terminal performance.

Built For Consistency

Hornady selected specific powders and primers for optimal batch-to-batch performance, so you're not gambling on variance round to round. The brass casings are quality stuff—new production, boxer primed, and reloadable if you're into that. Whether you're running this suppressed or unsuppressed, the low flash signature keeps things civilized. The load meets or exceeds FBI Protocol terminal ballistic test requirements, which is the real measure of defensive ammo reliability.

Works Everywhere

This ammo doesn't require a suppressor to function properly, though it really shines when you bolt one on. Pair it with a quality can and you'll get genuine quiet—subsonic rounds don't produce that sonic crack that still hits your ears even with a suppressor. Without one, you still get reduced noise and recoil compared to standard .40 loads, making it solid for home defense or controlled range work.
