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 - #6-32 x 7/16" IP15



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.

  • Sig P365 slide

    Posted by Richard Widner on Jun 3rd 2021

    The milling and crekote looked great. Fit was flawless, came with a new set of mounting screws. Lead time was pretty spot on if not little early. Very easy transaction and good all around experience.

    I was VERY pleased with how my slide looks and with how the Holosun fits. And it came back to me with the Holosun mounted. I was disappointed, however, the sights came back in a plastic bag rather than being remounted on the slide as I'd expected. I understand they have to be removed to do the milling and coating, but expected them to be mounted on its return. I should have specified that though, as I am pretty confident they would have remounted them had I asked. The service is excellent.

  • Hell yeah.

    Great finish. Great price. Lead time was a little long, but of I'm being honest, it was worth the wait. Thanks again guys. I'll definitely be using your services in the future.

    The work was flawless and completed faster than I had initially thought it was going to take. Will definitely use Jagerwerks for any milling work that I need in the future.
