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 Or 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.

    Its almost too good to be true. The cerakote, milling and the turn around time were all exceptional.

    I just received my slide back with optic installed. In less than 2 weeks as well. This thing is awesome. I can't wait to put rounds through it. Cerakote is perfect and milling is incredibly well done.

    Glock Mill and Cerakote

    Posted by Kevin Bearden on Jul 21st 2018

    Sent my slide off to Primary Machine to have it milled for a red dot and cerakoted. It was a 13 day turnaround from the day I shipped it to the day I received it back, you can't beat that. Mill job was a perfect fit, Red dot snaps right into place. Cerakote also looks great. I couldn't find a single spot that didn't look perfect. I would highly reccommend Primary Machine to anybody. On a side note, check that your dot is tight before you go and shoot it. I assumed it would be but noticed it was loose after shooting it about 100 rounds.

    Customer service is above and beyond professional. Open communication and replies to inquiries. The slide milling service is beyond comparison. Every aspect of the work is done with exacting tolerances, professional finishing and attention to detail. Turn around time was remarkably fast and a preasant surprise. They just earned another life long customer.

    g19 Slide milling/Coating

    Posted by Jake P. on Jul 9th 2018

    Primary Machine is an amazing shop. Bruce was readily available to answer any and all questions (within a 3-5min. time window mind you) and provide responsive and helpful customer service. To top it off, their shop lead time is ridiculously fast and turns out amazing results. I recently had a g19 slide milled and coated and it turned out phenomenal.

    Thank you again to Bruce and everyone at Primary Machine for your outstanding work!

    After searching everywhere I finally found a business that was capable and confident they could turn my Glock 23 slide into what would be considered an mos slide except better as it is precisely milled for my optic , it looks factory and functions flawlessly

    Quality as expected

    Posted by Trey on Jun 19th 2018

    Optic fit is perfect. Gun is new so the slide is extra tight right now but should break in just right after a couple hundred rounds. Pretty quick turn around. Will do it again with another pistol.
