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.

    many places will say an optic on a glock 42 can't be done. well that is not correct at primary machine !!!! i can no longer see iron sights perfectly and love red dots on all my guns. now i have one on my 42 as well. excellent work and the cerakote job was amazing as well. thanks to all of you !!!!

    Great Job. I received my slide in under two weeks. This was milling and cerekot. Great Job. I will do business with you again.

    This is the second optic slide milling Primary Machine has done for me. They did an excellent job, and completed in minimum time. The Cerakote finish excellent also. I wouldn't hesitate to recommend or use them again.

    Slide mill/cerekote

    Very pleased, and impressed with Primary Machines work. My G23 slide came back in pristine condition with a tight fitting rmr and a beautiful cerekote job. Turn around time was exquisite and they didn’t hassle me about my redneck packaging. Couldn’t recommend anyone better.

    Glock milling

    I sent in my Glock 19X slide to be milked for the trijicon SRO, with the Glock FDE cerekote. Workmanship and quality were outstanding!!! Got it back only 15 days after I shipped it, this included the thanksgiving day week. I will be sending in several more slide to be milled for an optic! If you need slide milling done for an optic, this is the place to send it! Outstanding job!!!
