We check out G9 Defense’s new all-copper subsonic 9mm self-defense ammo.

When it comes to 9mm ammunition, most shooters usually only need it to be either good for self-defense or subsonic, but those who need both in the same package have a new option to consider from G9 Defense. Featuring all-copper projectiles, it's as effective on target as it is quiet (when used with a suppressor).

The G9 Defense subsonic 9mm ammo is loaded with 126-grain solid copper External Hollow Point (EHP) projectiles, and they offer several advantages compared to traditional hollow point bullets. The parabolic flutes on each projectile utilize fluid dynamics to create devastating cavitation and wounds in soft tissue while their solid construction allows them to penetrate common barriers without performance loss and only minimal deflection when striking auto glass. G9 Defense says that the design of this bullet also helps prevent over-penetration and eliminates the possibility of jacket separation. The ammo has an advertised muzzle velocity of 1,020 fps, but the company recommends only using it with barrels that are 8 inches or shorter to ensure it stays subsonic.

The final impressive detail regarding G9 Defense’s subsonic 9mm ammo is that it’s light-for-caliber. Most subsonic 9mm ammo is loaded with 147-grain projectiles, but G9’s 126-grain bullets will be comparatively softer shooting and have less muzzle rise.

Effective on target, extremely quiet when suppressed and softer-shooting than most other subsonic 9mm, it seems that the G9 Defense copper subsonic ammo is going to be a great option for anyone running a suppressed 9mm for home defense. It’s available now and has an MSRP of $36.99 per 20-round box.
