Glock Stealth Comp (1/2-28) *Back In Stock!*

5 Stars

Product Description

- Machined in house from 7075 T6 billet aluminum

- Hard anodized finish

- Fits 9mm barrels with 1/2-28 threads (NOT for .40S&W!)

- Will fit Glock 34/35 holsters when installed on Glock 19 and 23 with 9mm conversion barrel

- Set screws are under the comp to keep a cleaner look

- Includes instructions and EVERYTHING needed for install 

- Installs in about 2 minutes

- Dimensions: 1" Wide (Identical to a 9MM Glock slide) X .785" Tall X 1.150" Long 


*We tested several brands of factory 115gr ammo with a factory recoil spring in a Glock 19 with zero issues.

*Remanufactured ammo is known to be loaded weak and may cause cycling issues. 

*Always test that your ammo cycles fine before carrying with Stealth Comp. You may need to go down to a 15lb or lighter recoil spring if you're seeing cycling issues.

*Cerakote will add 3-5 days to ship time.*


**These are made for 9MM GLOCKS ONLY. While they will fit any 1/2/28 9MM threaded barrel, we CAN NOT guarantee proper function with other guns and we will NOT accept returns on comps bought that did not work on other guns!**

  1. Good God This thing is cool. 5 Star Review

    Posted by on Jul 11th 2017

    So i wont lie. I initially purchased this because it looks badass and finished my custom 19 perfectly. I wasn't expecting too much in the performance department.

    But man was i wrong! When i went to the range to test this new sexy piece of machinery i compared it to my moms almost stock glock 19 and i can say without a doubt this thing shoots heaps flatter than previously.

    id give it a 6/5 but that would be a tad redundant.

    Can't thank primary machine enough!

  2. Works as advertised 5 Star Review

    Posted by on Jul 5th 2017

    Running this on an American Tactical barrel in a gen 4 Glock 17.
    Function perfectly with Herters brass 115 gr 9mm. Works just
    like a comp on an AR15. Greatly diminishes felt recoil

  3. Great machine work, fast shipping 5 Star Review

    Posted by on Jul 2nd 2017

    Machine work is super clean, chamfered edges match ZEV slide pretty well. Extremely fast shipping. Very happy with experience.
    I have shot hand loads from 90gr to 147gr with factory recoil spring. No issues at all.

  4. Perfect fit and look ! 5 Star Review

    Posted by on Jul 1st 2017

    Super fast shipping fits on my custom milled out g19 like it was meant for it. I havent shot with it yet waiting on my springco spring to come in. Will post an update after i dump sum mags.

  5. Sick with it!!! 5 Star Review

    Posted by on May 30th 2017

    Glock 19 gen4 stock internals - works, used a 15# recoil spring, ejects at 4/5 o'clock. (perfect)

    glock 34 gen 4 not stock at all - cycled correctly after install of a 11# recoil spring in my set up...

    matched perfectly with my slides which were milled out. customer service is top notch. nothing else to say but grab one...or two...like i did! you wont regret it. plus the tapering of the top edges reduced the snag unholstering the weapon. resulting in not needing to buy another holster.

  6. Great Comp - Good Quality 5 Star Review

    Posted by on May 1st 2017

    Definitely a great product designed with quality in mind. Watch the installation video, let the loctite dry, and let the fun begin.

  7. What Recoil?! 5 Star Review

    Posted by on Apr 24th 2017

    Received the comp in just two days after placing my order, super fast shipping. Fit and finish is excellent and yesterday my new comp'd 19 had its first range session. 750 rounds later and I'm sitting here wondering where all my recoil went?! :)

    Keep up on the great work Primary Machine!


  8. Awesome 5 Star Review

    Posted by on Apr 22nd 2017

    Love it bought two already

  9. EXCEPTIONAL 5 Star Review

    Posted by on Apr 20th 2017

    Received the comp very quickly, what surprised me is the coating, Gorgeous! The installation video is on point. But what also stood out is the attention to detail and tje packaging, comes with 2 vials of lock tite and a Allen screw. Can't wait to see how it performs!

  10. Excellent work 5 Star Review

    Posted by on Apr 15th 2017

    I recently had Primary Machine mill my Glock 17 upper and ceracoat it. Several days later I had to have the comp. I had it done in the same color as the slide and was blown away when it arrived in 4 days. The color match was perfect as was the milling. I cant recommend Primary Machine enough. If you buy any Glock accessory buy it from them.
