Frequently Asked Questions

What are the main methods for mounting a red dot sight on a pistol?

The primary methods include frame adapters that attach to the accessory rail, rear sight dovetail mounts replacing the rear sight, custom slide machining for a direct mount, and factory optics-ready systems like Glock MOS which use interchangeable plates for different optic footprints.

What are the pros and cons of custom slide machining for red dot sights?

Custom slide machining offers the most durable and lowest profile mounting solution for red dot sights. However, it is more expensive and requires a commitment to a specific optic footprint, limiting future optic choices.

How does a Glock MOS system differ from custom slide machining?

Glock MOS systems use interchangeable adapter plates to accommodate various optic footprints, offering flexibility. Custom slide machining involves directly milling the slide for a specific optic, providing a more robust and lower profile mount but less flexibility.

Why is co-witnessing important when mounting a red dot sight?

Co-witnessing allows you to see your iron sights through the red dot optic's window. This is crucial as a backup aiming method if the red dot fails, ensuring you can still accurately engage targets.
