If holster wear/durability is a concern then we highly recommend going with our Black Nitride as Cerakote is a wearable item. 

Cerakote and Black Nitride are for the entire slide. (Black Nitride adds 2-3 weeks lead time) 

For Cerakote color codes and examples: https://jagerwerks.com/cerakote/

It is implied that the customer will have arrangements for coating of a slide if NONE is selected for color. If NONE is chosen there is potentially an issue for rust and corrosion to develop on the slide. Jagerwerks is not responsible for misuse and neglect of bare metal. 

We do not charge extra for disassembly/reassembly, if you send your entire slide assembly we will laser align the sights for you.

If you include new sights we will install the new ones at no charge. If you include your 509T, barrel and recoil spring we will align it for free. 

If your iron sights are not compatible with the optic/optic cut we will not reinstall them. They will be sent back in a plastic bag with your slide.

The depth of the cut at its lowest point is .250"

The front edge of the optic cut is angled to allow for easier install of the 509T. This will not affect reliability or function of the optic/gun.

If you want lower 1/3rd co-witness iron sight you can purchase them below. You will need a .225" Glock rear and a .220" Glock front.

** Cannot apply optic cut to the Glock 17L and 41**

  • 509T slide milling

    The workmanship is amazing! With the high quality precision milling, my standard height sights are at a lower third co-witness to the HOLOSUN 509T optic. I am very impressed with the attention to detail. Keep up the great work. I will recommend your services to anyone I come into contact with.

  • 509T Optic Cut

    Posted by Michael on Jun 11th 2021

    I did my research and believed Jagerwerks to be my best option for an optic cut. Then, decided on the optic. I waited about 6 weeks to get my slide back and boy...was it worth the wait. The optic fits into the cut perfectly. The Tungsten cerakote is flawless. I don't know what else to say. Other than trust these folks to do you right. I couldn't be happier.

  • Perfection

    Absolutely fantastic work... The ultralow cut makes the chunky boi 509T sit amazingly low on the slide. Well worth the time and the money!

  • Nice deep 509T setup

    Got my slide cut for the 509T and Nitride, and Jagerwerks did an awesome job. I'm impressed with the very deep ride of the optic for a low-profile setup. And, of course the craftmanship, coating, customer service are all top notch. Thanks y'all!
