The Sig P320 is one of the most popular handguns in America. Available chambered in numerous popular cartridges and boasting excellent ergonomics and reliability, it’s hard to talk about P320 upgrades simply because the gun is engineered to a high level of exacting performance.
With that said, one of the most practical upgrades you can make to your P320 is a barrel, especially if your current P320 has one that’s not threaded.
For that, visit NineX19 and take a closer look at their Match V2 and Revolution threaded barrels. Here are some of the benefits that accompany this upgrade.
Enhanced Accuracy
NineX19’s P320 barrels are manufactured in the United States from stress-relieved, heat-treated 416R steel, with a 1:10 twist rate and a deep-cut target crown.
This fairly aggressive twist rate performs well with 9mm, and has been specifically chosen so as to offer the best (and most consistent) performance overall with the widest range of bullet weights.
As for the target crown, it’s been optimized for match-grade accuracy, whether you’re engaging targets at point-blank range or farther off.
Superior Heat Dissipation Properties
NineX19’s Sig P320 barrels are fluted – you can choose your choice of pentagonal flat fluting or spiral fluting, depending on the model.
If you’re not familiar, fluting is the process of removing steel from a gun’s barrel. Flutes are often straight or spiraled, but can also be geometric in nature or follow other patterns.
As you might expect, since fluting removes stock from the barrel, mass and therefore weight diminish. This makes the gun lighter, which though usually negligible in a handgun can make quite a difference in a rifle.
But the real draw here, with respect to the P320, is that fluting increases the surface area of the barrel, which gives it a superior ability to shed heat.
This keeps the barrel cooler during high-volume shooting sessions, which mitigates thermal stresses on the barrel and can also preserve accuracy, especially if you’re shooting at intermediate ranges.
Expandability
Sig does produce threaded barrels, but if you have one without a threaded barrel, there are aftermarket P320 barrels that are threaded (like those mentioned here).
A threaded barrel gives you the ability to expand with muzzle devices like suppressors and muzzle brakes which can cut back on muzzle pop and also reduce recoil and muzzle flip.
The Cost-Effective Route
Arguably the most important reason to upgrade to a P320 barrel from NineX19 is the cost factor. Sig’s own replacement barrels are very expensive; NineX19’s are remarkably competitive on price.
If you’re looking for a barrel that performs on par with the brand itself, or even outperforms it, this is one to look into.
