Beretta M9 Threaded Barrel
June 6 2017- Place order from Brownell’s for Silencerco threaded M9 Beretta replacement barrel.
June 7 2017- Brownell’s sends confirmation email that order has shipped, provides tracking number.
June 14 2017- 0900 Track package, FedEx says it was turned over to USPS and delivered to Michigan. I don’t live in Michigan, so there is a problem.
1030 Have discussion with USPS clerk at local post office. Informed that FedEx put my package in the “wrong sack” and sent it to Michigan. Assured that Michigan USPS would forward it to me in Wyoming, soon.
June 19 2017- 1055 Package from Brownell’s arrives via USPS. (Checked label. Yes, Brownell’s put my correct address on the shipping label, FedEx just screwed up.)
1710 Step out to the workshop to change out the standard factory barrel for the new Silencerco threaded version.
June 25 2017- 1630 Take Beretta M9 with new threaded barrel, AAC TiRant silencer, and can of subsonic 9mm ammunition to the Spur Outfitters pistol range.
1805 Police up the brass, testing completed.
Summary:
You might be wondering why, at this point in time, would I decide to put so much effort into the Beretta M9. Afterall, didn’t SIG just get the contract to replace the M9? As a matter of fact, yes they did and this is actually a great time to focus on the Beretta pistol.
One can never tell what the U.S. Government is going to do, but it is a safe bet that a good percentage of the U.S. Army M9 pistols will end up on the surplus market. For the most part, what that almost always means to the American gun buyer is good deals on used guns.
The first thing you should understand something about ordering replacement barrels for M9 pistols, most do not come with a locking block assembly. That’s cool, if you have had your M9 or 92 for a while, now is a good time to replace the locking block. Brownell’s has a locking block replacement kit. Beretta also has an online video to help you complete the installation.
Swapping out the locking block and plunger is not really that tough, but you need to have the right sized punch and pay attention to what you are doing. (Follow directions you mongoloid)
Naturally, as my pistol was completely disassembled, I took the time to clean it and apply FrogLube Extreme to the appropriate areas. You guys should know by now that I use FrogLube on the inside of my .22 LR and pistol silencers as well.
Initial Conclusion:
I primarily used subsonic 9mm ammunition for the testing, though I added a few rounds of super-sonic for comparison. The new 9mm Honey Badger load from Black Hills uses a 125 grain, solid copper projectile (not compressed powdered metal). This load is subsonic and it ran like a champ in the M9 with the AAC can in place. The combination of the pistol, new barrel, and silencer ran flawlessly as a result.
For those of you wondering about using the factory sights, I can tell you that Zach and I both had no trouble ringing the steel silhouette target from 20 yards. I started at 10 yards and kept backing up by ten yard increments. When I reached 40 yards I found that I was having difficulty keeping rounds on the silhouette. In conclusion, I suppose that’s pretty respectable using the factory irons which sit below the outline of the suppressor.

Can you say anything about the differences in the two barrels. Were you able to get further out with the orig barrel or with the new silencer ready barrel with or without silencer. You said you tried the supersonic as well as the subsonic, any differences.
Good point on checking and replacing the locking block and plunger. Very good Flash report on changing the barrel of the M9.
Enjoy the show…
When I have ordered stuff from Midway USA it has fedexd from Colombia MO past Indiana to Columbus OH USPS then back to Indiana. I am hoping M9 s hit the surplus market soon, id like to rebuild one with the Wilson Combat custom 92 parts, those make for a sexy little gun.
