In a post last year, we identified some issues with the newly released Ace Trigger system, namely the lack of a functional trigger safety. NROI has worked with TriggerTech to correct any deficiencies, and they have released a new trigger system with an external safety lever that satisfies USPSA and SCSA rule requirements for primary safeties. The new model is called the “TriggerTech Certified Special Ace Trigger System for Glock”.
Go here for a statement from TriggerTech regarding the changes and the company’s policy regarding replacements.
The new trigger system is approved for USPSA and SCSA use in Glock firearms, as it meets the existing rule requirements for primary safeties.
