Please Note: This is a machining service only. You are sending us your slide and in some cases your optic as well — the optic and slide are not included with this service.
Our cuts are precision CNC machined to exact tolerances using our cradle cutting method, which keeps the footprint intentionally tight. This ensures your optic locks in solid with little to no movement once mounted.
When applicable, we also add precision-cut recoil bosses. These help direct the stress of recoil into the slide, not just the screws — giving you better long-term reliability under heavy use.
Whether your setup is for competition, duty, or everyday carry, our optic cuts are made to hold up to serious firing schedules without shifting or loosening.
⚠️ Important: After machining, the cut exposes raw metal. We strongly recommend selecting one of our coating options to prevent corrosion. If you choose “No Coating,” you're accepting the risk of rust or finish damage from moisture and exposure.
***For customers purchasing the C series optic cut in order to use the 509 adapter plate, the standard cut will not be the correct length. If you want to use the adapter plates, please specify this intent in your individual order notes. The cut will be cut slightly oversized for their plate (your C series optic cut will NOT have a tight fit).***
For Customers getting a 509T Milled, our cut has a relief on the right corner. This is by design. This is not a mistake, nor sloppy machining, its due to the nature of the mounting system. The picture below is a reference of what the cut will look like once complete.

Slide Milling and Optic Mounting
I just received my G45 back after having the slide milled and Holosun dot sight mounted. The turnaround time was far faster than the estimated lead time. The overall quality of the milling, cerakoting and optic mounting is excellent. Vulcan performed the same work on my G43X, my EDC, and it’s been flawless both in daily carry and the pistol course I ran it through shortly after getting it back. Definitely money well spent.

Installation of Holosun Red Dot onto Glock 19x Slide
Summer of 2022, Vulcan Machinewerks installed a Holosun optic onto my new Glock 19X slide. It seems to be solidly mounted and aligned well, but perhaps my inexperienced expectations were expecting too much as I am a little (not a lot) disappointed. The cut to the slide to hold the optic was not even to the optic on both front sides. Rather , while flush and perfect to the shape of the optic on one side, on the other there is a small gap where they obviously made a little mistake which isnt too noticeable if you arent looking to inspect it but very noticeable if you are. It is either a mistake …or a purposeful stray from perfection because perfection is just too hard when mounting such an optic- I dont know. Also this brand new, never used optic came back with two corners of it scuffed to where the underlying silver metal shines through rather than still retaining the black coating it came with new - also not too noticeble but definitely scratched from the wrench or vice or whatever they used to hold and install it. Maybe this is how all such work results no matter who you use??? All in all still worth it because …who else will do it for me? So I thank them but the quality of work wasnt what I expected. Functional yes and that is what counts, but not beautiful. Vulcan Feedback: For the Optic, we use this type of cut for the 509T because of the mounting system. The relief on the right side is to help roll the optic in place and not a mistake on our part. We have also offered the customer a free replacement optic.

Holosun Optics Slide Cut
I dropped off my Glock 19X slide with the guys at Vulcan to have them mill the slide for the installation of a Holosun Optic. The work was first class and the slide was returned to me with fresh Ceracote which very closely matched the original color. Overall a great job. The time frame to get the slide in line to do the work was about 3 weeks.
