I notice a small but very wise production change on the slides of the Glock. On the G23 a small area has a bevel instead of being sharp and edged at 90 degrees. Under magnification, the edge looks almost burnished right wear the slides used to batter out. A light burnish, or surface corner break. This absolutely cuts down on slide peening. This is a significant albiet small production change that should enhance the gun. Very hard to see and I needed magnification glasses to view the burnished edge. The newer Glocks should show even less then adverage slide wear. A good move on Glocks part.
