Size Chart


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

Lead time is 3-4 weeks. 

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.

  • Black Nitride

    These guys do the best job. Amazing customer service. Honest and fair pricing. Can’t imagine going anywhere else. Nitride came back flawless.

  • Black Nitride Finish

    Posted by Brandon on Mar 17th 2021

    Absolutely perfect! Took about a month to receive my slide back, which was right on time with their initial estimation. It looks even better than a factory glock finish to me. Will definitely be sending more slides their way. Do not hesitate to business with these folks! Top notch all the way around.

  • Glock 48 Nitride

    Posted by Tom on Mar 6th 2021

    I didn’t care for the silver look on my Glock 48 and it wears quickly. I sent my slide in for the nitride finish and am very pleased. This is the second one I have had done.

    I had black nitride applied to my Glock 43 slide after Jagerwerks enhanced my rear serrations. Absolutely perfect finish!
