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.

  • P365 Romeo Zero Optics Cut

    Very happy with the Jagerwerks workmanship. The nitriding looks at least as good as when I took the pistol out of the box brand new. I sent my whole upper in and really appreciate how they aligned the red dot, barrel, sights. Due to the ammo shortage due to the China Virus I've not been able to shoot it yet, but I've used my "laser cartridge" for lots of dry fire practice, and it is dialed in great. All things considered here in 2020, I was pleasantly surprised at the turnaround time - wasn't expecting it for another 2-3 weeks (took only about 3-4 weeks). You've another satisfied customer! Thank you.

  • Romeo Zero milling and finish for Sig P365

    The milling work and metal finishing were first class. The barrel alignment was extremely close with the Romeo Zero dead in at 10 yards. would use them again. Highly recommended!
