Buffalo Bore Ammunition 24J20 Subsonic Strickly Business 9mm Luger Subsonic 147 gr Full Metal Jacket Flat Nose (FMJFN) 20 Per Box/ 12 Cs

Buffalo Bore Ammunition's Subsonic Strictly Business 9mm Luger is purpose-built for shooters who need reliable, quiet performance without sacrificing stopping power. These 147-grain full metal jacket flat nose rounds are loaded to subsonic velocities, making them ideal for suppressed firearms, hearing protection-free shooting, or any scenario where noise matters. Whether you're running a dedicated suppressor setup on a duty or defense pistol, training indoors, or shooting in noise-sensitive environments, this ammunition delivers consistent function and accuracy while keeping the decibel count manageable.

The 147-grain weight is the subsonic sweet spot for 9mm—heavy enough to maintain energy and stability at subsonic speeds, yet proven in countless platforms. The flat nose profile enhances terminal performance over traditional round-nose designs, and the full metal jacket construction ensures reliable feeding and durability across autoloaders. Buffalo Bore's reputation for quality control means you're getting ammunition that cycles reliably, shoots to point of aim, and groups tight enough for precision work.

Packaged in boxes of 20 rounds with 12 boxes per case, this is serious ammunition for shooters who know what they want and don't compromise on consistency. If you're running a suppressed 9mm and tired of commercial subsonic loads that short-change you on performance, Strictly Business is worth a closer look.

Frequently Asked Questions

Will subsonic 9mm work reliably in my semi-automatic pistol?

Subsonic ammunition is generally reliable in most modern 9mm autoloaders, though some guns with very stiff recoil springs may require a lighter spring for consistent cycling. Test a box first to confirm reliable feeding and extraction in your specific firearm.

What's the difference between subsonic and standard 9mm ammunition?

Subsonic rounds are loaded to velocities below the speed of sound (roughly 1,125 fps), reducing the supersonic crack that occurs when a bullet breaks the sound barrier. This makes them excellent for suppressed shooting and noise-sensitive applications, though they carry less energy than standard loads.

Can I use subsonic ammunition for self-defense or duty use?

These are full metal jacket rounds designed for target practice and general shooting; they are not expanding ammunition. Consult your local laws and your firearm's manual regarding suitable self-defense loads for your jurisdiction and use case.

How much ammunition is in a full case?

Each case contains 12 boxes of 20 rounds each, for a total of 240 rounds per case.
