Ron, yes Sir. You will need to replace the Rear Sight with a Dovetail Optics Mount as demoed here : https://www.youtube.com/watch?v=8QSxdZY723c&t=27s

Ron, Here are some dovetail mounts that work:--------Sawke Glock Sight Mount Plate - Glock 17 19 22 23 26 27 34 Mounting Plate for Mini Red Dot Sight,Glock Mount Plate for Red dot Burris Sightmark Vortex ----------------UTG Super Slim RMR Mount for Glock Rear Sight Dovetail Hunting Trophy Mounts ---------------Ade Advanced Optics glock Tactical Mini Dotx Sight Pistol Mount Base --------------EGW Glock Sight Mount For the Docter, Burris Fastfire, Vortex Venom & Viper

Gen 4 Glocks do not have optic cut outs. One would either have to purchase a mount that sits in the rear sight groove, or purchase a G5 MOS
