The SHIV 9mm suppressor is a small yet lightweight solution engineered for exceptional performance with 9mm pistols and pistol-caliber carbines. Made with premium 3D-printed Grade 5 (ELI) Titanium, the SHIV weighs just 2.5 oz. It offers durability, excellent sound suppression while maintaining semi-auto pistol function. The low weight, and short length eliminates the need for a booster on most 9mm pistols. Why Choose the SHIV? The SHIV 9mm suppressor combines our trademark creative engineering and 3D printing to deliver a lightweight yet robust suppressor. The SHIV removes the complexity of a booster system. The SHIV is meant to be small and compact, it is riding the razor’s edge of performance with its mass and length. Reliable cycling on pistols hinges upon Not only the mass of the suppressor, the location of the center of mass. We have done our homework to give you the best possible balance of sound performance and reliability on your semi-Auto pistol.    Note: The Glock 19,17, and Glock 34 are the most sensitive pistols for cycling with suppressors (even with a booster). Main spring weight may need to be reduced to ensure reliable cycling due to variables in shooter recoil management and low pressure range ammunition. We have found in some cases that there is a break in period of 30-50 rounds.  CALIBER: 9MM, .38 SPECIAL, .357 MAG, 300 B.O. SUBSONIC, 5.7×28.
