Cerakote is for the entire slide. 

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.

Trijicon RMR cut with front posts. You are able to use Trijicon supplied RMR screws. Cut at .125" 

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 RMR we will align it at no charge.

Using Ameriglo SG-181 you will have a lower 1/3 co-witness.

A Sig rear dovetail will be milled for the rear iron sight.

    Recently had my P320 slide milled for the RMR with the top window and slide serrations along with the iron sight in front of the optic. Everything, including the creracote, has an amazing fit and finish. Would recommend to anyone looking to mill a slide. Fast shipping and great customer service as well.

    Excellent work and cerakote, very speedy turn around time only took 12 days to get the slide back from confirmation of delivery. Will definitely be coming back in the future.
