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 .215" Glock front.

https://dawsonprecision.com/dawson-precision-glock-standard-front-sights/ .215" front 

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

** This is NOT the same footprint as the Primary Arms HE509-RD ACSS Vulcan**

  • Great Job

    Posted by RICHARD on Mar 13th 2022

    They did an excellent job on my slide cut and mounting of my sights and optic. I will use them again. It took a little longer than I would have liked but I had the slide recoated, so I guess you have to expect that. I am pleased with the results.

  • Social media worries were unfounded

    Posted by Tom on Feb 11th 2022

    I was initially nervous about shipping my G20 slide out to some company I've never worked with. This was compounded by some social media threads I was reading about really long wait times and lack of correspondence. I am happy to say that these complaints were completely unfounded based off my experience. My order was completed way ahead of expected wait time. Jagerwerks support was transparent and communicative the whole time. I could not be happier with the quality of the cut and the nitriding. Time will tell how well it the nitride holds up but they corrected some wear on the slide that was there when I sent it in but gone when I got it back. If I chose to have any more of my pistols cut for optics, Jagerwerks will be my first choice and I'll sing their praise from the mountaintops to anyone who will listen.

  • Glock 509T cut

    Posted by Trey Waterman on Feb 4th 2022

    The milling work that Jagerwerks does really is second to none. It’s low and tight to the slide, the rear sight cut is secure when you move it in front of the optic, it’s clean with no tooling marks left. You honestly could run regular height sights and take the optic out and it wouldn’t look bad at all. My only complaint is whoever Jagerwerks has do their parkerization; when coming back to me looks absolutely terrible. I had to silicone wipe it so bring it out. Now it’s not that big of a deal but upon first impressions out of the box looks bad when you’re paying extra for it.
