HK VP9 Optic Milling

(120 reviews) Write a Review


Model: HK VP9 & SK

Service: CNC Mill Slide For Optic (Optic MUST Be Sent With Slide - No Exceptions)

Sight/Co Witness Notes: Our Sights Will Only Work With Trijicon RMR & Holosun 507/508.

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.

    VP9SK/ Black Nitride coating

    Posted by Cody Merle on Mar 16th 2021

    This was my first order with primary machine and I can say it will not be my last. After reading everyone's reviews I felt very confident in them to perform my slide milling, and no one was wrong. Fitment, quality and finish are excellent. I was a little confused on the lead times tho, I thought it was 4-6 to be milled and additional 6-8 for the nitride coating. I mailed my slide in on 1/22/21 and was back in my hands milled, finished and optic installed on 3/15/21. I had both Trijicon RMR and suppressor height sights installed. Thank you Bruce and the Primary Machine folks, excellent job!!

    Beautiful work. My RMR fits perfectly and the Cerekote is flawless. It only took about 3 weeks, which is pretty fast.

    HK VP9 with Holosun 507k

    Machining was done with amazing accuracy. Cerakote finish is uniform and quality feeling. Lead time was WELL below what the website estimates. Slide comes back in a protected tube in the box. Will be doing all of my pistols with Primary Machine.

    Amazing work! The milling is perfect and the Cerakote is flawless! I received my slide back in under 3 weeks from my ship date. PM is the only place I’ll send my gun parts to, I couldn’t be happier!

    HK VP9 RMR cut

    Posted by Brian Russo on Jan 31st 2021

    I am so happy with the job that was done. It only took 3 weeks and is expertly and precisely machined. It arrived and was packaged very safely. I could immediately tell the quality of the work. I have already put 200 rounds through it and it has perfumed flawlessly. I would highly recommend Primary Machine for any machining and firearm work.
