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: https://jagerwerks.com/cerakote/

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. 

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 509T, barrel and recoil spring we will align it for free. 

If your iron sights are not compatible with the optic/optic cut we will not reinstall them. They will be sent back in a plastic bag with your slide.

The depth of the cut at its lowest point is .250"

The front edge of the optic cut is angled to allow for easier install of the 509T. This will not affect reliability or function of the optic/gun.

If you want lower 1/3rd co-witness iron sight you can purchase them below. You will need a .225" Glock rear and a .220" Glock front.

** Cannot apply optic cut to the Glock 17L and 41**

  • 509t cut with Black Nitride finish.

    Posted by Chad on Oct 15th 2021

    Excellent customer service and craftsmanship for my 509t and Bob cut. I was told to get the black nitride finish if holster wear and durability is a concern. So of course I opted for the black nitride. The only down fall was that the slide has a flat and dull appearance and has already shown signs of wear and scratching of the slide, with normal holstering and unholstering in one range day. I miss the Gen 4 factory coating, after years of owning and using the gun it was still shiny and smooth with minimal wear.

    Absolutely perfect. I expected top quality based on reviews, but this really exceeded expectations. I sent my 509t in with my slide and it came back mechanically zero'd, only needed 2 clicks left to group where I wanted it. It's a rock solid mounting, low to bore axis, and has this optic presenting with a very natural point of aim rather than "teetering on top" of the slide like other RDS's i've shot with. I love the 509T because of it's invincibility, now with this milling I can trust that the rest of my system will be equally up to the task. Well worth the wait!!!

    The milling was first rate, their response to emails is terrible but could be do to staff shortages

    Outstanding job. This is my third slide cut, first with Jager, and I’ll keep coming back to them for the rest.
