    My second V3 cut, this time I went with the Black Nitride, it was definitely worth the extra wait! It looks great!!

    This is my second slide from Primary Machine. They do a quality job and have great customer service. You will NOT be disappointed.

    I shipped my slide to Primary Machine on Nov 7th and was notified it arrived to them on Nov 9th. Fast forward 6 days the slide arrives at my door all the cuts are perfect, no tooling marks what so ever and the cerakote milticam job is better then I could of hoped! Primary Machine took my “Block” slide and made it sexy as hell! All in one week, all my slide from now on will be going to Primary Machine!

    Amazing work and fast turn around. Decided to give Primary Machine a try after hearing good reviews. The quality of work is superb, and I will be sending in another slide. Initially I was apprehensive about the cost, and sent in a slide for a gift project, but after seeing it first hand my own will be on the way soon enough.

    UCC V3 cut Glock 19 Gen 5

    I cannot be more happy about the work that was done on my slide! I modified my order to omit the window on top of the slide and add serrations. It looks outstanding! Cuts are smoothed and finished. The RMR cut is very precise and the cerakote job is perfect. The lead time was very impressive as well! They received my slide on a Monday, and the next Monday they were shipping it!
    I will definitely recommend them first for any slide work!

    UCC V3 on Glock 19 Gen 5

    Got this cut on my glock 19, gen 5 in sniper grey. The cuts are high quality and smooth - i don't see any sharp edges or imperfections. The slide feels significantly lighter over stock and man this thing looks awesome on my gun

    Outstanding Service and Equally matched Customer Service!

    After shopping around for slide/optics cut, I was able to message and speak with the Primary Machine team, where they helped answered all of my questions, leaving me reassured that they were a legitimate and professional business, not some guy with a dremel making slide cuts.

    Words like impressed and astonished are barely able to describe how I felt when I gotten my slide back! Their workmanship shines thru! Very happy with how everything is milled with precision and cerakoted. I had cerakote jobs done by a "basement gunsmith" which turned out crappy.

    Took less than 3 weeks from start to finish and worth the research, time, and money spent on it!

    The team at Primary Machine is LEGIT!!!
