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**

    Excellent fit and finish and having the rear sight located to the front works great with the Dawson Precision sights I got with the cut. Still very happy with the end result a couple years later.

  • Slide milling for Glock 20 Gen IV

    Posted by Robert on Dec 28th 2023

    I grew tired of waiting for Glock to release an Glock 20 MOS, so I bought a Gen IV with the intent of having the slide cut for an optic. Of course Glock introduced the Gen V MOS a month later. I found Jagerwerks and reached out. I was hesitant to send firearms across country because last time I did that, Springfield Armory sent an M1A I was having serviced across the country to a complete stranger. Jagerwerks had great customer service; they explained the process, alleviated my concerns, and communicated throughout the process. Turn around time was respectable and the work has been superlative. My Glock 20 now has a Holosun 509T on it and over 1000 rounds of "real" 10mm later, she's still straight and tight, with no issues. I couldn't be more satisfied and I highly recommend Jagerwerks!

    Slide work and Black nitride finish looks amazing. Turn around time was better then I expected. And I didn't make it easy on these guys. I wasn't aware of all the options and changed my order 3 times. And they worked with me so well. I can't recommend them enough. Amazing company to work with.

  • Holosun 509T cut for Gen3 G34

    Other than the typical 8 weeks wait, this is my second optic cut from Jagerwerks, many shops do optic cuts, but very few will actually do black nitride, which is superior to cerakote, install your iron sights, install and laser bore sight in your optic, money well spent.
