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 Zero, barrel and recoil spring we will align it for free

Sig Romeo Zero - #6-32 x 7/16" IP15


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.

    I’m extremely happy with the Jagerwerks workmanship. The nitriding looks very good, I sent my entire upper in they aligned the red dot, barrel, sights. Considering how we’ve been on lockdown for a year now, Jagerwerks got my slide up and running in a very reasonable amount of time, at a very reasonable amount of money. I’m extremely happy with their work, Thank You very much Jagerwerks!

    Thank you Jagerwerks, for my P365 with the optics cut that Sig still fails to offer. The milling, fit, finish and assembly are perfect. Thank you Jagerwerks!
