TTI has been producing subsonic ammunition since it’s founding and produces and sells more purpose-built Subsonic ammunition than all others combined. The reasons is simple; our primary design goals for our Subsonic ammunition are; consistency, accuracy and function. In tactical applications, accuracy and consistency are paramount. Our subsonic rifle ammunition will shoot MOA and even Sub MOA in rifles capable of that accuracy, which is why TTI Subsonic ammunition is recommended by most major suppressor manufacturers. Our highly accurate and consistent Subsonic ammunition is the result of hundreds of hours of research, development and testing. We test for function and readability with a wide variety of weapons and suppressors. TTI Subsonic Pistol ammunition is designed to properly cycle the actions of most properly functioning pistols and sub machineguns.
