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

Cerakote is 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

  • P365 mill work

    Posted by James Angotti on Nov 16th 2020

    What an absolutely amazing job! I sent my slide barrel & spring with a halosun micro dot, & Ameriglo suppressor sights. Jagerworx’s Milled the slide, mounted the red dot, mounted the sights, sighted them in & zeroed it all perfectly. It’s tight clean & looks great. Shot perfect groups right out of the box.

  • Amazing quality work

    Sent my p365 NRA edition in to have the slide milled for the Holosun micro red dot. I was concerned to see if the color could be matched and the quality of work looks like it came this way from the factory. Very impressed.

  • Awesome

    This was my 3rd slide done by jagerwerks. Like always the quality is top notch and my optic mounted straight up
    With no issues. Cerakote work was nice as always.

  • Will use Jagerwerks again!

    This was the first time I've had a slide milled for an optic and I wanted to use a trusted name in the industry and I'm glad I did. The craftsmanship is excellent and the fit was perfect. It took less than the 6 week estimate which was also a nice surprise. I was also pleasantly surprised to see the necessary torx driver included for the set screws. I'll definitely use Jagerwerks for my next mill job.
