ForseMark Ammunition

It's not for everyone. Built to Serve Those Who Serve™

QuietStrike™ is engineered for professionals who operate in environments where stealth, control, and terminal reliability must converge. Whether executing a high-risk warrant, conducting surveillance, or maneuvering through confined urban spaces, this subsonic 9mm cartridge delivers discreet power with uncompromising performance.

Designed for law enforcement officers, tactical teams, and authorized military personnel, QuietStrike™ combines soft nose expansion with bonded core integrity, ensuring maximum stopping power while minimizing acoustic disruption. It’s a purpose-built solution for suppressed platforms and close-quarters engagements—where backdrop sensitivity, overpenetration risk, and auditory control are mission-critical.

Why Subsonic Matters

Supersonic ammunition produces a ballistic crack that defeats the purpose of suppression. QuietStrike™ eliminates this acoustic spike by maintaining subsonic velocity, enabling:

• Reduced sound signature through suppressed firearms
  Improved team communication during dynamic entries and engagements
  
  
• Minimized auditory disorientation in enclosed or echo-prone environments
  
  
• Enhanced tactical discretion, especially in surveillance, warrant service, and sensitive urban operations
  
  
• QuietStrike™ allows operators to maintain stealth without sacrificing terminal performance—making it ideal for agencies that prioritize both discretion and decisive threat neutralization.
  

Terminal Behavior & Tactical Fit

Unlike barrier-blind or armor-piercing rounds, QuietStrike™ is engineered for controlled expansion and predictable wound profiles. Its soft nose design initiates expansion upon impact, transferring energy efficiently while reducing the risk of overpenetration.

This round is especially suited for:

• Tactical entries and warrant service with suppressed weapons
  
  
• Urban law enforcement operations requiring stealth and backdrop control
  
  
• Domestic military use under Hague-compliant protocols
  Close-quarters engagements where precision shot placement and acoustic control are essential
  
  
• QuietStrike™ supports mission success without compromising officer safety, civilian protection, or legal defensibility.
