The Certified Special is a one-piece trigger with a pivot safety for smooth engagement, encouraging consistent trigger pulls. The trigger is USPSA approved and allowed in ISPC Standard, Optics, and Open divisions. It also has a backplate with a relief pocket that increases clearance to the striker under extreme shock conditions. No changes were made to the Sear module. Overall, these updates greatly improve drop safety and impact durability for the ACE Trigger System.
