Frequently Asked Questions

What are the steps to install an optic on a Glock Gen5?

First, ensure the firearm is safe and clear. Disassemble the slide, remove the recoil spring assembly and barrel. Remove the cover plate screws, select the correct optic plate, and install it. Then, mount the optic using manufacturer-provided screws and torque them to spec. Finally, reassemble the slide onto the frame.

Which optic plates are included with Glock pistols for optic installation?

Glock pistols typically ship with three optic plates: Plate #2 for standard RMR footprints, Plate #3 for C-More footprints, and Plate #4 for Leupold/EOTech footprints. Always check your specific model's inclusions.

Do I use the original cover plate screws to mount my new optic?

No, the screws that come with your Glock pistol to secure the slide cover plate are not used for mounting an aftermarket optic. You must use the screws provided by the optic manufacturer.

What is the importance of torque specifications when installing a pistol optic?

Adhering to the torque specifications provided by the optic manufacturer is critical. Overtightening can damage the optic or slide, while undertightening can lead to the optic shifting or coming loose during recoil, affecting accuracy and reliability.
