Barnes Suppressor Series Sierra 9mm Luger 147gr JHP Subsonic Ammo, 20-Round Box

Barnes Suppressor Series 9mm Luger 147-grain Sierra Jacketed Hollow Point ammunition (part no. 32522) is a subsonic-optimized defensive load from Barnes, built specifically for suppressor-equipped pistols and carbines. The line pairs premium Sierra projectiles with clean-burning propellants loaded to Barnes’ exacting standards, reducing gas blowback and improving cycling reliability in semi-auto platforms while delivering a noticeably quieter shot through a suppressor. At 147 grains, this is the classic subsonic 9mm weight, staying below the speed of sound in virtually any barrel length so shooters get the full noise-reduction benefit of their can. It’s a strong choice for a suppressed 9mm pistol or carbine kept ready for home defense.
