Description
This True Precision barrel transforms your P320 Compact into a more refined shooting platform without any gunsmithing. The barrel is precision-machined in the USA from certified 416R stainless steel and finished in black nitride for durability and corrosion resistance. The broach-cut rifling profile is engineered to handle all types of ammunition safely, from standard jacketed rounds to cast lead loads and defensive ammunition.
Enhanced Feed Reliability
The feed ramp geometry on this barrel is specifically designed to promote consistent feeding across the widest variety of ammunition types. True Precision refined the chamber angles, added chamfers, and improved the radius cuts throughout the barrel to deliver better performance than OEM standards. This means fewer malfunctions and more confidence in your gun, whether you're training at the range or carrying for protection.
What Sets This Barrel Apart
Aftermarket barrels are machined to tighter tolerances than factory versions, which translates to better lockup and superior accuracy potential. The proprietary broach-cut design allows the barrel to work reliably with cast ammunition, giving you flexibility in what you shoot. At 3.9 inches, this barrel maintains the compact handling of your Compact or X-Carry while delivering the performance improvements you'd expect from a match-grade upgrade.
Installation and Compatibility
This is a true drop-in barrel—no modification needed for most P320 Compact, X-Carry, and M18 slides. If your gun has a loaded chamber indicator, you may need to remove or modify it slightly to avoid interference. The barrel comes with a proper SAAMI spec chamber and features a 1:10 right-hand twist rifling for solid ballistic stability across 9mm loads.

Frequently Asked Questions
Will this barrel fit my P320 X-Carry or M18?
Yes, this barrel is designed to fit the P320 Compact, X-Carry, and M18 models. Most X-Carry models will fit right away, though some older variations may require very minor fitting. It will not fit the X-Compact (which uses a 3.6 inch barrel).
Do I need a gunsmith to install this barrel?
No, this is a drop-in barrel that requires no modification to install. Simply ensure your firearm is unloaded, remove the slide from the receiver, and slide out the old barrel and drop in the new one. If your slide has a loaded chamber indicator, you may need to remove it as newer True Precision barrels are designed without the LCI hole.
What ammunition can I safely shoot through this barrel?
The broach-cut rifling design allows this barrel to handle standard jacketed ammunition, cast lead rounds, and defensive loads safely. The SAAMI spec chamber ensures proper pressure and performance across reputable 9mm ammunition manufacturers.
How does this barrel improve accuracy compared to stock?
Aftermarket barrels like this one are precision-machined with tighter tolerances than factory barrels, which improves lockup and reduces inconsistencies in the barrel-to-slide fit. Combined with the proprietary broach-cut rifling and refined chamber geometry, this translates to tighter groupings and more consistent performance on target.
