ZEV created the market for upgrade triggers for GLOCK. Over the years our triggers have won more world championships and are in the hands of more professionals than all other after-market triggers combined. We didn't stop there. Beginning two years ago we set out to reinvent our entire product line. 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. NOTE: ZEV Technologies recommends this for competition use ONLY. The ZEV Trigger bar is in our small frame trigger kits only (9mm/.40)
