Our optics cuts are precision CNC milled to exacting tolerances to give you industry leading performance. A primary feature of our cradle cutting method is the fact the optic will be tight in the cut and will have extremely little to no ability to move once in place (this is by design). Our cuts will also have precise and consistent recoil bossing (where available) to add strength to the cut. This is to ensure the repeated reciprocal forces from firing are not translated exclusively to the mounting screws. No matter if you are in military/law enforcement community, competition community, or personal defense community, our cuts will ensure your optic survives the harshest of firing schedules. 

P220/225/226/227/228/229 will have an exposed Safety Block after the optic cut. If we do not have your optic to mount after the work has been completed, you have to insert your Safety Block Spring then mount the optic to hold that assembly in place. P226 Optic Cuts are limited due to the lightening pocket on the underside of the slide. If you're unable to selcet a certian combo of optic and 226, this is why.

***For customers purchasing the C series optic cut in order to use the 509 adaptor plate, the standard cut will not be the correct length. If you want to use the adaptor plates, please specify this intent in your individual order notes. The cut will be cut slightly oversized for ther plate (your C series optic cut will NOT have a tight fit).***

*Optics Not Included*


For Customers getting a 509T Milled, our cut has a relief on the right coner. 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.

    SIG P229 Optic Cut for Holosun 507K

    Published by David Huie on May 9th 2024

    Vulcan Machine Werks did a magnificent job with the optic cut. I'm very happy that I went with the DLC recoating option. It matches the original factory coating in color. The lettering on the slide was still visible and sharp after the recoating. Ross keep me informed with the progress of my order. They have my future business and referrals!

    P365 slide cut

    Published by Clint on Apr 25th 2024

    Solid work and worth the wait. Good snug fit fit for the optic, locked up perfectly. Cerakote finish was top notch and probably as good or better than factory. Purchase the service with confidence.

    Published by David Ortiz on Dec 5th 2023

    The Vulcan Machine Werks team did a phenomenal job. The optic is mounted securely and the cuts are clean and well done. The DLC job is phenomenal. No cloudiness or haziness. It's an immaculate looking finish.

    Sig Slide Optic Cut

    Published by Stephen Tryon on Aug 17th 2023

    This isn't my first rodeo with Vulcan Machine Werks. I have had around four slides cut by them. This one was beyond those satisfied experiences. Mailed in two Sig P365 slides and they were delivered on Monday. On Wednesday I received an email saying they'd shipped me a package. I called to see if it was just a label being created (a common habit of many companies) and to my shock they related that the slides were done and were on the way home. To say I'm satisfied is a major understatement and yes I will use them again (and again) in the future.

    Vulcan was able to work with me on doing an k footprint cut on a unique sig 250 platform. They delivered more than once and did it fast and well.
