    UCC V3 for G34

    Posted by Jonathan on Feb 11th 2020

    Completely changed the look and performance of my G34. Cerakote was flawless. Turnaround time was nothing. Great company and quality work.

    UCC V3 slide milling

    Posted by Unknown on Aug 19th 2019

    I dropped off my Glock slide for the slide milling,red dot milling, and Cerakote. It was finished in 7 or 8 days (outstanding), and was every bit as great as I had hoped. All of the cuts were smooth, and the overall look was impressive. 10/10 would use Primary Machine again.

    UCC V3 Glock 17L

    Fast turn around (3wks) looks fantastic! I can’t say enough. I’ve had slides milled by other companies and Primary Machine has the quality, price and return time

    Great quality slide work !

    Posted by Cameron on Mar 11th 2019

    I sent my slide out and had it back in 2 weeks and I was super impressed with the quality work done by these guys. Took it out to the range and the gun cycled flawlessly for over 300 rds. I would recommend your service to anyone looking for slide work.

    UCC V3 G19 Gen 3

    UCC V3 on G19 Gen 3
    -sniper grey
    -RMR cut
    -irons forward
    -ameriglo all black supp height sights

    Just rolled a little over a year anniversary on the UCC V3. The G19 gen 3 has been my EDC for several years, but after the Primary Machine magic the slide cycles faster due to the lightening cuts, chamfers, and pockets (and looks stellar!), but functionally it makes for faster follow up shots. The slide itself weighs about an ounce less than OEM and that's including a Trijicon RM07. Precision milled RMR cut with recoil bosses and the sniper grey cerakote is holding up nicely considering I am not easy on my EDC. It sees around 300 rounds a month with very little to no cleaning between range sessions and even more dry fire reps and it just works! I have several other "builds" from a stock G17 gen 4 to a Roland Special 19x and other non glocks, but the Primary Machine G19 still holds the EDC crown. Overall top notch workmanship at a great price with a fast turnaround. Need to send in my p10c for the Omen V2 treatment next!

    Slide work

    Posted by Jose Guerra on Oct 25th 2018

    I reached out and had a few questions about the slide machining and rmr cut. I sent a question concerning my G19C slide as I wanted the UCC V3 cut but was worried it could not be done due to the factory ported slide. Bruce got back to me within the hour. Granted this was around 9-10pm my time in Southwest Texas. I was so impressed by the willingness to answer a POSSIBLE customer that I was already sold. Bruce gave quick and simple answers, which had me going to the post office the next day to send out my slide. The cuts were amazing, he left the factory cuts in place but they fit the rest of the slide perfectly. The cerakote job was amazing as well. All in all I am very impressed and pleased with my purchase. In my honest opinion if you are on the fence about sending your already expensive slide in for work do it. You will not be disappointed. Also turn around time was less than 2 weeks including shipping and in transit time for me. Sent my slide in on a Saturday, it was recieved that Tuesday. By the following Wednesday it was at my door.
