Patriot Defense | 9mm Barrel Reaming (Hard Coating/Melonite/DLC)


This service is for 9mm barrels with a hard coating.

We utilize our custom 9mm Match Finish Reamer to ensure we bring your undersized chamber back to SAAMI spec while still maintaining the accuracy you demand. Chamber will be sized properly and the “leade” lengthened to allow a much greater range of projectile and OAL to be utilized. This service will greatly increase reliability in guns with short or no “leade” and has no negative affect on accuracy. Usual turnaround time is less than 24hrs - 48hrs and pricing includes return shipping back to you.


Please mail your barrel to with a copy of your invoice enclosed:


3352 County road 212

Anderson, TX 77830


*Please ensure barrel is clean when sending or an additional cleaning charge may incur. 

*Please ensure barrel is properly packaged when shipped to prevent damage during transit

    I have been having problem using a JHP bullets before it was reamed, now it’s working flawlessly. Service was fast and delivered back to me less than a week.

    Hardened Barrel Reaming

    Posted by Robert T on Feb 2nd 2023

    PD returned my email inquiry asking if they could handle CZ Shadow 2 barrels. That's the barrel no one wants to touch - even those who say they can do 'hardened' barrels. They said no problem . I sent mine in and with about a week turnaround time, I can now load out to reasonable length 1.135 - 1.1500 depending on the profile. No detriment to accuracy either.

    So I was very happy with the services rendered. The day they received my barrel it was shipped out the next following day. Thanks for getting this typically impossible task done!

    Ream/freebore barrel

    We all know that many companies in this industry aren’t that great about answering emails/inquiries. Patriot replied to my question about this service the same day and turnaround couldn’t have been faster.

    9mm G19 barrel throat too short

    Posted by Andy on Oct 14th 2021

    Would not allow 9mm factory or reload rounds to chamber. PD reamed just enough to allow proper chambering of rounds. Quick turnaround and reasonable cost.
    Would definitely use their service again if needed.

    Barrel Reaming

    Posted by Tom on Jul 19th 2021

    For some reason, my Shadow2 Optics Ready pistol would not feed and function well with 135gr JHP ammunition.
    I shot Carry Optics in USPSA and this was very frustrating.
    A fellow competitor recommended Patriot Defense since he had the same problems with his Shadow2.
    I went on their web site and ordered up the barrel reaming, and it was very easy.
    I sent in the barrel and the same day it was received at Patriot Defense I got an order update and then the work was completed the same day and shipped back to me the same day.
    I got the barrel back and went to the range to check functionality…..over 150 rounds there with no malfunctions.
    I shot a local USPSA match a few days later, round count was 185, and agin hand no malfunctions.
    Patriot Defense does very good work and they were fast…..if I need more work in the future they will be the first place I check.

    A Must!

    Posted by G “Switch” on Jul 15th 2021

    Sent 3 barrels to get reamed, should have done it a long time ago! I’m able to load to 1.1250 instead of 1.08 and able to use different bullet profile!
