Guy at work recently turned me on to the Tango Down Vickers slide racker. This replaces the striker plate and provides additional surface area to assist in power stroking the slide. It has helped with training stoppage clearance in the 45 for me and guys at work I’ve had run it. If you personally have no issue with this then good for you, drive on. I nor anyone that I know who actually use Glock pistols for a living have ever had problems with erratic ejection or brass to head or face. We don’t study ejection patterns either, so long as the brass clears the chamber and the pistol continues to cycle we’re good to go.
