The Heckler & Koch LEM Trigger Conversion Kit is a specialized internal component upgrade engineered to transform standard DA/SA or DAO fire control groups into HK's proprietary Law Enforcement Modification system. This factory OEM parts kit combines the safety advantages of a double-action-only stroke with the crisp, clean break of a pre-cocked striker-fired trigger. Designed to provide a highly uniform and consistent trigger pull weight from the first shot to the last, it significantly mitigates the traditional accuracy disturbance experienced during double-action transitions. The unique design also retains crucial restrike capability, allowing the operator to immediately press the trigger a second time in the event of an ammunition-related failure to fire. Composed of a precision-machined hammer, cocking piece, and corresponding springs, this kit provides a smooth, duty-grade feel that elevates shootability while preserving all factory internal drop safeties.
