ZEV Technologies Glock trigger kits and components cover the complete trigger assembly from shoe to connector. Drop-in trigger kits deliver reduced pre-travel, lighter pull weight, and a positive reset without voiding Glock's action warranty for competition use. Individual components — connectors, trigger bars, and springs — allow incremental tuning for shooters who prefer to build their trigger feel layer by layer. Legal for USPSA Production, CO, and IDPA divisions. Fast same-day shipping on most orders at Shooters Connection.
