After thousands of hours of design and engineering and after hundreds of thousands of rounds of testing, we are proud to announce a product line built from the ground up to perform better and more safely than anything else on the market. ZEV Trigger Bar: the ONLY professional GLOCK replacement trigger bar that reduces travel, and provides professional, crisp trigger pull while keeping all factory Glock safeties intact. Our Triggers feature a wider trigger pad and safety for better user engagement and offer drop-in functionality with improved ergonomics and a clean, crisp creep free trigger pull.
