The Thin Blue Line Series from Apex Tactical offers an enhanced, black trigger with a blade-in-trigger safety that is blue. Each year, between 140 and 160 officers perish in the line of duty, and Apex vows to donate 25 percent of each Thin Blue Line Series trigger sale to Concerns Of Police Survivors (C.O.P.S.), an organization dedicated to supporting law enforcement. As of this writing, the triggers are available for Glock and Smith & Wesson M&P pistols. apextactical.com
