Patriot Defense | 9mm Barrel Reaming Service

Patriot Defense | 9mm Barrel Reaming Service


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 and pricing includes return shipping back to you.


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


3352 CR 212

Anderson, TX 77830

    Tanfo chamber was jamming with reloads of various types. I was told that the chamber needed to be reamed. Club personnel suggested Patriot Defense do the work.

    I have chamber checked numerous reloads that were jamming and all easily fit into chamber. Problem solved. The work was done with extremely fast turn around and the value for money was definitely a big plus. I will pass this info to friends and will also shop Patriot Defense for future parts and services. Very friendly people to work with as well. Exceeded my expectations.

    9mm barrel reaming service

    Posted by Werner Ostmann on May 5th 2021

    This service was performed quickly, and I got my barrel back fast. Before reaming my reloads that would pass through my chamber gauge, but about 10% would not pass the "plunk test". I even had some rounds that would jam the gun out of battery, leaving a live round jammed in the chamber. This created a dangerous situation when removing the round. After I got the barrel back it worked flawlessly.

    Barrel reaming 9 mm

    Posted by William on Jan 25th 2021

    The entire process, shipping and return took
    7 days. The barrel looks great, I think they even polished the feed ramp. It made it much easier to load bullets with different ogives that will pass the plunk test.

    Great service and fast turn around time. Sent in 2 very tight CZC Bull Shadow barrels and had them back within a few days. Would recommend to anyone that needs barrel reaming done.

    Awesome service

    Posted by Joey Barcinas on Apr 25th 2020

    was intially hesitant with having the barrel reamed. I sent my barrel to get done on Monday and was expected to arrive at PD on Tuesday. I was checking to see if they recieved it and already got a return tracking. Extremely fast and quality work. I'm now able to load longer and did not compromise accuracy. I would recommend highly to those that are thinking about it but worried. Its well worth it, thanks Patriot Defense!

    Doesn't get any better than this

    My Tanfo Stock 2's slide would not close when I put in Round Nose reloads. I sent my barrel to Patriot Defense on a Monday and got back my barrel on Friday of the same week. Patriot Defense has amazing customer service and they are very personable. I would recommend Patriot Defense and getting your Tanfo barrel reamed in a heart beat!
