Model: All Generation & Model Glock (No 42. 43 Is Milled For Shield RMS Or J POINT Only)


Service: CNC Mill Slide For Optic (Optic MUST Be Sent With Slide - No Exceptions)


Finish: Cerakote Or Black Nitride


Other: We mill precision pockets for your optic! While many companies will mill an over sized "one size fits all" pocket, ours is precision as per your optic. The cycling of a pistol slide is not gentle. The last thing you want is all that force to simply be on the mounting screws due to an optic pocket milled too big! Screws have been known the shear and break over time due to improperly milled slides.

Configurations For Co Witness Sights Using Suppressor Height Sights:

Trijicon RMR Holosun 507, Vortex Viper: Optic can be milled in front of rear dovetail or have rear dovetail milled out and mill new Glock dovetail in front of optic.

Vortex Venom, Burris Fastfire III, And Deltapoint Pro: For lower 1/3 co witness, you MUST mill out the rear dovetail and mill new glock dovetail in front of optic. You MUST use plain black suppressor height sights.

If you are not worried about iron sights, any configuration is fine.

    I can’t say enough how pleased I am with their workmanship and detail. Very great job and even when it was returned they took pride in packaging it up to keep it from getting damaged.

    Ecstatic with the milling done for my Glock 45, the installed Holosun 507c is snug and secure in its custom milled and supportive pocket. Will definitely recommend and use Primary Mavhine in the future.

    G22 slide optic milling

    This was my first time mailing out parts for service, the company communicated well prior to me sending my slide, the turn around time was as advertised, the quality of the mill work and cerakote was fantastic, I’m blown away by the precise fit of the vortex optic to the slide and the cerakote (burnt bronze) finish is perfect, I’m more than satisfied and if I choose to have another slide milled I wouldn’t hesitate to send it to Primary Machine.

    Glock Slide milling and mount red dot

    This is the first time I have had slide work, so I was a little nervous. The instructions for shipping my slide were clear and simple. The price was within my budget. The work was performed in the time promised, and when I received the finished product, it exceeded my expectations. The cerokote made the slide look like new. The Holoson 507c v2 was fitted so closely, it looked like part of the slide. At the range, the slide functioned flawlessly. I doubt slidework at twice the price would be any better.
