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:

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.

Screws supplied are (2) #6-32 IP15. Both are safe to use on the extractor side of the slide. An IP15 is needed for install 

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 K series, barrel and recoil spring we will align it for free

Holosun K Series / EPS / EPS Carry - #6-32 x 7/16" IP15


Note* Please be careful when installing screws with the new EPS, tolerances can be slightly different and the screw caps come close to the glass.  If JagerWerks does not do the installation we cannot guarantee fitment.



Iron Sights:
 is a great option for a lower 1/3rd co-witness. If you include these with your slide we will install them for free.

  • Excellent Work

    I'm very pleased with the milling and nitride coating. My Holosun 507k fit perfectly! My only complaint is that they did not re-install my iron sites. They were sent back in a bag with the slide, and were not easy to install without a sight pusher.

    The slide turned out amazing and the red dot is seated well. Couldn’t ask for better service from these guys. This is my second purchase of slide milling and I’ll definitely be back for the next one.

    Long wait but worth it. My slide looks like brand new, plus red dot cut is perfect. Thank you for sending screws for red dot.
    I would recommend this company to whoever needs job like this to be done on their pistol. I feel like I have a new pistol, amazing work.

    Had my 365 milled for a Holosun 507K. It took a little longer than I hoped, but I understand manpower issues in the current state of the country as well as the volume of demand. Slide machining and Nitride coating was flawless. Cleaned it, assembled the optic and the gun functions perfectly!
