Most Helpful Positive Review awesome barrel
Well just an fyi YOU HAVE to remove the Loaded chamber indicator (very easy) to install this barrel or it will not work/cycle. Youtube it the "Sig guy" has a video on it all new replacement barrels of all brands that Optics Planet sells for most Sigs NO LONGER have the LCI cutout. Other than that really nice solid well built barrel with a thread protector with a rubber o ring. The color is more like copper than bronze or tin but very attractive thought it was going to clash with my P320 M-18 FDE but its acceptable and with the mini compensator by griffin armanent in black it fits together we...

Upgrade M18

by RMC, Verified Owner from NV, United States Written on November 23, 2025
This barrel is a definite upgrade from the OEM I put together a M18 I use this barrel with a Harrington arms, compensator,Grayguns full size grip module, and a little bit of trigger work. Don’t get me wrong. The M 18 is a decent firearm, but this puts it on another level.
Pros:
  • All good.
Cons:
  • No complaints you get what you pay for.
Best Used for:
  • Range gun or EDC you pick.

True Precision Sig Sauer P320-M18

by ShooterSean, Verified Owner from IA, United States Written on November 27, 2024
This barrel dropped right into my M18 no issues. I did have to remove the LCI but that was a 2 min fix. My Rugged Obsidian 9 threaded right on with no FTF or FTE issues. Shipping from Optics Plant was also super fast!

Finish is not great

by Mike, Verified Owner from ME, United States Written on November 12, 2024

Quality Fit & Finish

by SClark, Verified Owner from OR, United States Written on October 24, 2024
This barrel has an even nitride finish, mates up with the host well, and didn't cost a ton of money. I paired it with a Herrington Arms compensator. The reason I give this product 4 stars is because the threaded section is too long. The threaded section extends into the compensator's port cavity, which will not allow for the full degree of compensation.
Pros:
  • Price
  • Finish
Cons:
  • threads too long
Best Used for:
  • Sig P320 Compact
Would recommend: Yes

Great barrel to pair with a compensator

by Alex, Verified Owner from TX, United States Written on February 1, 2024
I have a P320 Specter Compact that is a 3.9 length barrel. This barrel fits great and is very accurate shooting tight groups at 25 yards.
