Atomic Ammunition 9mm 147gr JHP subsonic defense ammo combines hearing-safe suppressed shooting with reliable hollow point expansion for the quietest effective self-defense round in 9mm.
Buy 9mm subsonic defense ammo from Atomic Ammunition. Our 147gr JHP bridges the gap between suppressor-optimized subsonic ammo and genuine self-defense capability. The heavy 147gr hollow point expands reliably at subsonic velocity while keeping your suppressed carry gun whisper-quiet. This is the round for shooters who carry suppressed and refuse to choose between noise reduction and terminal performance.

Subsonic Performance & Applications
The 147gr JHP is the heaviest standard 9mm bullet weight, and at 980 fps it’s naturally subsonic — no sonic crack, even from longer barrels. Combined with a suppressor, this round reduces noise to hearing-safe levels (under 130 dB from a pistol). Despite the lower velocity, the 147gr weight provides adequate penetration (12–14 inches in gel) and the JHP design ensures expansion for effective energy transfer. For suppressed carry guns like threaded Glocks, Sigs, and CZs, this is the quiet self-defense round that actually works.

Frequently Asked Questions
Will this cycle my semi-auto pistol?
Yes. Our 9mm 147gr subsonic is tuned to reliably cycle standard semi-auto 9mm pistols, including compact and subcompact models.
Is 980 fps fast enough for JHP expansion?
Yes. Our JHP projectile is specifically designed to expand reliably at subsonic velocities, unlike standard JHPs that require higher velocity to mushroom.
How quiet is this with a suppressor?
Expect 125–130 dB from a suppressed pistol — similar to a car door slamming. Standard 9mm without a suppressor is 160+ dB.
Is the brass reloadable?
Yes. New boxer-primed brass, fully reloadable.
What is the minimum order?
Minimum order is 100 rounds. Bulk discounts on 200+ rounds.
