  • Optic Milling For Glock Pistols


Model: All Generation & Model Glock (43, 43X, 48 Is milled for 407K/507K, or RMRcc, 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 507/508: Optic can be milled in front of rear dovetail or have rear dovetail milled out and mill new Glock dovetail in front of optic.

Deltapoint Pro: For lower 1/3 co witness, you MUST mill out the rear dovetail and mill new 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.

    Quality work & quick turnaround

    Posted by John on May 20th 2024

    I'm very impressed with the quality work done on my slide. I appreciate having to send MY red dot with my slide, to be assured it fit exactly as necessary so as to fit & function properly. Turnaround of 4-6 weeks was originally estimated. I received it within that time. Awesome job Primary Machine!

    The milling, alignment and Cerakote are Perfect. ^^^

    Cut slide for Holosun green dot dot

    Posted by Michael Komendo on Jan 24th 2024

    Over all the workmanship was great and I would have given a 5 on the rating but there was two problems. First the rear suppressor sight was not installed with no explanation why. Secondly the Allen key that goes with the rear sight was not returned with the rear sight. Fortunately I have a glock sight tool and was able to install it and a Allen key that fit the rear sight otherwise I would have had to take my slide to a gunsmith which would have
    cost me more expense.

    2nd slide with PM

    Posted by James Marsella on Jan 15th 2024

    This is my second optic cut with PM. The first for a CZ, the second for a Glock. Both were very well done and I could not be happier. The service and quality of their work is top notch and receiving the slides sooner than the quoted time is a bonus. If I had more slides, they would sent to PM as well.

    First rate work. I am very happy with the slide I had milled, the cerakote refinishing and the installation of new iron sights.

    Excellent Service

    Posted by Derrick Medina on May 16th 2023

    Sent my Glock 19x in to get milled. These guys were very responsive to my emails and kept a clear line of communication with me throughout the process. Milling was great and also cleaned up my slide a bit which I was very appreciative of. Will definitely be doing business with them again. Thanks Primary Machine!
