Apex's Scott Folk walks you through the proper procedure for installing the Apex Competition Trigger Kit for the Ruger Mk IV and Mk IV 22/45 pistols. PLEASE NOTE: This is a very long video and we advise you review it first before starting on the install, Then, use the timecodes to take you to the relevant parts you need to watch or re-watch. There are two options for installing the hammer assembly, one with the Apex Mag Safety Delete and one using the factory Magazine Safety. Pick which you plan to go with before you start the project so you know where to jump to in the video.
