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.

    G19 Optic Milling, RMR Install and Stealth Comp

    Posted by Eric M on Feb 8th 2019

    This is my second job by PM and again they have exceeded expectations. I had the slide milling and RMR install done as well as a window cut in the top of the slide. The slide was cerakoted sniper grey. All of the milling and coating is exceptional. I also ordered a Stealth Comp (OEM profile) in sniper grey. The fit and finish on the comp match that of the slide. Watch Bruce's video and the install of the comp only takes minutes. I have several hundred rounds through the set up and no feed, fire or ejection issues. I am probably one of the more high maintenance customers that PM has due to my OCD tendencies, but Bruce's patience and response timing are exceptional just like their work! These guys do what they say in a very timely manner with no sacrifice when it comes to quality!

    I’ve had Glock slides milled for RMR and DPP by Primary Machine and they’ve all fit like a glove and been absolutely problem free. Primary Machine is THE place to go for optic milling as far as I’m concerned!

    Glock Slide Mill/Mount Job

    Posted by TCE-Michigan on Nov 5th 2018

    This is my 2nd Glock Mill & Mount job from Bruce and the Primary Machine Team. Supper Happy ! Always available, darn near instant responses for questions/updates (even late on a Saturday night !), Bruce must have his phone attached to his head. As with my first baby, the workmanship is flawless and looks like it came from the Factory this way. I had her home and back together inside of 6 weeks ! I would highly recommend Primary Machine and will utilize their impeccable craftsmanship in the future.

    slide cut

    Posted by JP Byrne on Sep 30th 2018

    You guys milled my G334 slide for a LDP dot.
    Job was flawless and it came back to me with the dot installed ready to shoot, and shoot it does !!! I opted to mill out the rear sight dovetail and am happy with that decision as it makes a much cleaner install, IMO.. I've had no issue whatsoever acquiring the dot without irons..

    I sent my Glock slide to Primary Machine to have it machined for my RMR. The turnaround was very quick and the machine is a perfect fit for the RMR. The finish great and accuracy is outstanding. I highly recommend this service.

    Vortex venom glock

    Posted by Andy K. on Aug 7th 2018

    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.
