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

Black Nitride adds roughly 3 weeks to your slide order. Items sent in only for black Nitride have a 3-6 week turn around time. 

The Salt Bath Nitride process is a Thermo Chemical treatment that improves wear resistance and corrosion resistance of ferrous metals with little or no dimensional change.

If you send in a slide that we do not offer milling for you will have to have it completely disassembled. Please remove the irons and all internals. If you fail to do this we will refund the order and return the slides.

  • Glock 19 Work...

    Posted by Adam Coker on Feb 21st 2022

    I sent my Gen 5 Glock 19 to Jagerwerks to have my slide milled for a Holosun 507C, Para top cut, Dawson iron sights and both the barrel and slide refinished in black nitride. The results far exceeded my expectations. The quality of work is by far the best in the business and their customer service was outstanding. It was worth the wait and I already have another gun on the way to Jagerwerks. I couldn't be happier and will be using Jagerwerks exclusively in the future. Hell I didn't even have to sight it when I got it back!!!

  • Nitride Refinish

    Posted by Matt on Feb 8th 2022

    The quality of the Nitride Finish is impressive. Absolutely, perfect appearance. This is the third cut and refinish in Nitride that Jagerwerks has done for me. As always, outstanding workmanship from Jagerwerks!

  • Black nitride Glock slides

    Posted by Robert on Oct 1st 2021

    Had a Glock slide black nitride by a different company & was disappointed. Then sent it to Jagerwerks who did it right. Then sent another slide to Jagerwerks & they did it right actually outstanding. The only place I will send future work will be Jagerwerks

    Looks great, can't find any imperfections. We will see how it holds up, but I'm not worried.
