Loaded with a \u003cstrong\u003e180-grain lead flat nose\u003c\/strong\u003e projectile, this round stays well below the speed of sound for quiet cycling through pistol suppressors, and the flat nose profile produces a wide, square meplat that delivers clean, predictable terminal performance.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eHSM rates this Subsonic \u003cstrong\u003e40 S\u0026amp;W\u003c\/strong\u003e load at \u003cstrong\u003e985 fps\u003c\/strong\u003e muzzle velocity, producing \u003cstrong\u003e388 ft-lbs\u003c\/strong\u003e of energy.

The moderate subsonic pressures are gentler on both the gun and the suppressor than hotter supersonic defensive loads, which makes this a go-to choice for suppressed range training, quiet target practice, and extended suppressed plinking sessions.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe lead flat nose projectile is a classic choice for reduced-noise handgunning: it stabilizes quickly, feeds reliably from standard semi-auto magazines, and holds tight groups at typical engagement distances.
