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.

  • Holosun 507K on Sig P365

    Posted by David Garlikov on May 23rd 2022

    Last year Jagerwerks installed a Holosun 507C on my S&W M&P 2.0. Now I decided to add an optic to my P365 carry gun. Based on the fabulous job that Jagerwerks did on my M&P, I never considered anyone else for the install this time. That paid off because I just got the gun back and it looks like the sight is an original part of the gun. They do unbelievable work and I would recommend them unconditionally to anyone. I don’t plan on purchasing another pistol. But if I do Jagerwerks will get it shortly after I’ve run the first few hundred rounds through it.

  • Holosun K series slide cut

    I Recently received my P365 slide back with the Holosun K series cut and couldn’t be happier. Very Clean work and the optic fit perfectly. I also can’t say enough good things about how the sniper grey color turned out. Highly recommended. I wasn’t expecting my slide back for 3+ months given the warning on lead times on the front page of their website. However, mine got back to me in just under a month. Very please with their work.
