My personal and work full sized Glocks are set almost the same, Glock factory (not sure who makes them for Glock) front tritium sight, rear is standard but steel. Under pressure I am really only worried about that front dot !! I have been back and forward with the extended slide release, none of my training sees me use it for a load/reload so I gravitate to the original as supplied part. My personal 17 has a 3.5lb connector the 22 has the NY1 arrangement. I have been looking into tungsten guide rods but have not ventured there as yet.
