The Apex Reset Assist Mechanism (Patent Pending) is a drop in part engineered to improve tactile trigger reset of your M&P pistol. Along with improving the felt reset, the Apex RAM also serves as a failsafe in the unlikely event of a Trigger Return Spring breakage; keeping the trigger bar properly positioned under the sear and allowing the user to manually manipulate the trigger forward between shots.
This product works in Smith & Wesson M&P 9mm/,357 Sig and .40 S&W models that DO NOT INCLUDE a thumb safety and DO NOT INCLUDE the Internal Locking System.
