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. The ZEV Technologies Fulcrum Adjustable Trigger is the premier Glock trigger kit for competitive shooters seeking to attain the ultimate performance from their pistol. The Fulcrum trigger features adjustment screws built into the trigger pad for fine tuning the pre-travel and over-travel of the trigger for personal preference. Trigger pull weight is determined by the trigger spring, firing pin safety spring, and striker spring and is not effected by the pre-travel and over-travel adjustments of the trigger pad.
