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

Cannot perform optic cuts on the P365-XL. 

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.

    I sent my P365 slide for nitride finish. My slide had already optic cut previously done at San Diego but they don’t offer finish. I am not not sure but it looks like Jagerwerks went extra mile and smooth out the optic cut and made it look excellent for a $25 nitride finish. It took only 4 weeks. I appreciate you just and you have great pride in what you do. I highly recommend Jagerwerks and by the way I am a first time customer and will send some more slides.

  • Very nice milling

    The Jagerwerks guys were very accommodating when I asked if they would be able to mill my P365 XMacro Comp slide. Turn around took about 2 months and the wait was definitely worth it.

  • Great Milling

    Sent in two P365 slides for the Holosun 507k race cut with nitride finish. Returned back in approx. 8 weeks, as expected. Excellent milling, fit and finish. Will probably do it again!

    Very friendly and super fast turn around on the slide milling with no coating.
