I recently installed the JG Vex shoe on my gen 5 17 and am failure to fire issues, when shooting groups and slowly pressing the trigger back. No issues when slapping trigger aggressively. Apparently this is caused by the interaction between the trigger bar and firing pin safety, and JG said timney has an upgraded bar to address. I had zero issues with the timney shoe. I checked the timney website and don’t see any upgraded bars available. Anybody have any recommendations?
