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.

Our Holosun K Series cut is milled to a depth of .125" which includes front recoil posts and mounting screws. 

Screws supplied are (2) #6-32 IP15. Both are safe to use on the extractor side of the slide. An IP15 wrench is included 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 Holosun, barrel and recoil spring we will align it for free. 

Works on Large, Medium and Small frame Glocks. 

Holosun K Series - #6-32 x 7/16" IP15 screws are included. 

For a lower 1/3rd co-witness you will need the irons listed below. If you include these with your slide we will install them at no extra cost. 

Rear iron sight - .225" / .125" wide

Front iron sight - .220" / .125" wide

Race cut (no rear iron) front sight - .190" / .115" wide

Shield RMS/c will fit this cut as well but  #6-32 x 3/8" IP15 screws are required. You can purchase Shield Screws here

Swampfox Sentinel will fit this cut as well but #6-32 x 3/8" IP5 (equal length) screws are required. You can purchase Sentinel screws here  

If your iron sights are not compatible with the optic/optic cut we will not reinstall them. They will be sent back in a plastic bag with your slide.

The $20 upcharge on the 17L/41 is for a stainless steel plug that we install on the underside of the slide. This ensures proper thread engagement.

    Couldn't be happier, the workmanship is flawless and the turn around time was exactly what they said it would be. Like a few other reviewers I'm going to send my G17 in now to get it milled too. I highly recommend Jagerwerks!


    Posted by Kevin on Jun 1st 2021 guys are top notch. The work on my slide was flawless. Installed included iron sites and zeroed the RDS....put a couple of magazines through it and it was dead on! Now I just gotta send my Glock 19 to you guys and get it done too...
