The Tyrant CNC Glock 43x & Glock 48 compatible slide cover plate is a 3D CNC machined back plate with a chevron design and chamfered edges. Meant for the Glock 43x & Glock 48 and made from aerospace grade aluminum, this anodized back plate adds a subtle but sophisticated appearance to Glock. Mix and match it with our other Glock components, or let it stand alone as the final touch for Glock 43x or Glock 48.
