Description
Apex Optic Mount for Holosun 509T Footprint Optics – Glock Gen 6 Pistols
Mount your Holosun 509T footprint optic directly to your factory Glock Gen 6 Optic Ready slide with this precision-machined steel mount from Apex. Designed specifically for the Glock Gen 6 optic cut, this mount provides a secure, repeatable platform for your red dot without requiring slide modification or adapter plates.
Why Steel Matters for Your Slide
A modern 9mm pistol slide experiences roughly 3,000g of acceleration with every shot. Aluminum mounts commonly fail under this force — during Apex’s testing, both 6061 and 7075 aluminum mounts showed rail separation from the base after only a few thousand rounds. This steel mount handles that stress cycle after cycle, keeping your optic zeroed and your pistol reliable. Machined from billet steel with a black PVD finish, it resists corrosion and wear far better than coated aluminum options.
Built for Real-World Use
- Direct fit: Works with Glock Gen 6 slides that have the factory optic cut. No plates, no adapters, no extra parts.
- Vibration dampening: A factory-placed damper sits in the cavity under the front of the mount to reduce vibration and close the light gap between the mount locking key and the slide.
- Install-ready: Comes with two 4mm x 0.7 mounting screws, each with high-temp thread locker pre-applied. Torque to 15 in-lb. Clean the slide surface before installation for best results.
- Made in the USA: Manufactured by Apex in Arizona from domestically sourced materials.
