    Slide serration and Holosun 507C milling

    Posted by John DeThomas on Jun 11th 2019

    The quality of the workmanship is excellent. The slide serrations match those of the factory. I also had Primary Machine cut my slide for a Holosun 507C and the fit is perfect. The Cerakote refinish quality is excellent as well. Primary Machine also installed my suppressor height sights and they were perfectly zeroed. Function was 100% when I tested out the slide. I am fully satisfied with the product and would not hesitate to recommend them. They will continue to have my business in the future.

    Perfect EDC mod

    Posted by Aaron Koch on Feb 5th 2019

    I got the serration package + chamfer package + RMR cut for my EDC Glock 19 and it’s ideal for my needs. The machining and cerakote is all flawless and the turn around time was about a week. I couldn’t be happier with the results from Primary Machine.

    I got these done as part of my "Fauxland" special build. All I have to say is great work. The serrations definitely help with weapon manipulation, but aren't overly aggressive or rough. I'd absolutely recommend these to a friend.

    Glock Serration Package

    Posted by Richard Lucas on Oct 15th 2018

    Had front cocking serrations added to my Glock 17 and refinishing in black nitride. The result is beautiful. I'll be sending a few more in the near future. Thanks guys at Primary Machine!

    Front Serrations with red dot cut and nitirding

    Posted by KRISTOFER on Jun 22nd 2018

    I am extremely pleased with the results. The front serrations are great. The Sheild RMS cut is perfect, tight fit with bosses. With the black nitride, my old 2 pin 3rd gen 19 slide looks brand new.

    Front serrations

    Posted by Alex on Apr 24th 2018

    Added. Front serrations along with the RMR cut to my G19.5 slide. Quality work, could not be happier.! This was my first milling job to any of my handguns and I am glad I chose Primary Machine.
