Cannot perform optic cuts on the P365-XL. 

Cerakote is 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.

  • Better than expected

    I had my 365 slide milled for the Romeo5 and it looks beautiful. The battle worn bronze cerokote sets it off! Now all I need is a threaded barrel and my carry is perfected! I did sent the sight it with it to be mounted and zeroed, not sure if it jarred in transit too much but it is way off.
    Thanks Jagerwerks.

    I got my P365 back a week ago and the work they did is fantastic. I love everything about it except one item that my not sure if it is because I had the optic cut in front of the iron sights. The 507K is designed to co-witness with the iron sights as it does fantastic with the P365XL. I wanted to keep the night sights on with the red dot but it does not co-witness at all. Other then that I love the other milling that was done to the side.

  • Beyond my expectations

    I had been wanting to get my standard P365 cut for an optic for some time but finally decided it was time. Decided to try JagerWerks based on their reviews and man, I am NOT disappointed. They were surprisingly fast (especially for our current gun climate) and the finished product turned out better than I would have hoped. The modifications look and feel great and their cerakote work is spot on. They even included the correct mounting screws for the optic I had specified in my order that I would be installing on it. 100% would recommend.

    Amazing job done by Jagerwerks with no flaws of any kind. The work was performed perfectly and quickly and my pistol slide was returned completely assembled and aligned.
