- CNC mill your Glock slide for your optic
- Cerakote or Black Nitride Refinish entire slide
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.
What to do after you order:
- Print order confirmation email
- Send copy of confirmation email with slide (does not need to be disassembled) and optic to:
2951 Railroad Ave
Morgan City, LA 70380
Current turn around time is 2-3 weeks.
- We WILL NOT mill deeper than firing pin block allows!
If you choose to mill IN FRONT of rear dovetail with the following optics, the firing pin block will be a limiting factor on depth, which is .050" deep: DP Pro, FF III, Venom
With that said, those optics WILL NOT co witness unless you choose the option to mill the rear dovetail out and mill new dovetail in front of optic. This allows us to mill the optic deeper and co witness with Ameriglo suppressor height sights. DP Pro will only co witness with plain black front and rear suppressor sights.

These folks are truly great at what they do. They milled my Glock 19 slide and threw on suppressor sights. They drilled through the rear iron sight (for a Vortex Viper). Absolutely flawless! Couldn't be better. True quality.
I sent in a Gen 4 Glock 34 slide to have a Trijicon RMR installed with the rear iron forward of the RMR. Service was within the time frame given, including the understood holiday delays. Upon receiving the slide, I was amazed at the fit and finish. The nitride coating is immaculate and the optic cut is precise. I would not hesitate to send another slide (or more) their way.
I purchased the optic cut and cerakote during the 10 days of Christmas. I was completely blown away by the turnaround and overall quality of work. My RMR fits perfectly with absolutely zero play. Outstanding company and outstanding craftsmanship!
Had a few questions prior to submitting order. These were quickly answered. The turn around for this work was less than 2 weeks. Customer is notified they have received your slide and optic along with progress of the work. Work is top notch!! Return packaging is very good. Would definitely recommend to others.
I was very pleased with how well the rmr cut was, but i was more impressed with the cerakote, i had a hard pattern but they did it like it was childs play. 5 stars for me
Decided to try out primary machine after the company I was using made a few mistakes. Glad I did. The milling work is top notch. The cerakote is perfect. Couldn’t be more impressed. I am definitely using Primary exclusively now.
Primary did a great job on my G29 Gen4 slide. Had them mill for my RMR Type 2 and then have it nitrided. Everything is great, machining, finish, and function. Reassembled my slide and test fired. Performed fine and my RMR was already sighted in. Would go to Primary again in a second. Total time was roughly 4 weeks which was what I was expecting.
Very good quality RMR cut. The optic fits very snug. There was one small flake in the cerakote job, but I may have chipped it. Not sure.
Great job! Quick Service!
