Whether you're running factory FMJ, hollow points, or cast lead ammunition, this barrel handles them all, making it an ideal upgrade for shooters who want better performance without compromising function.

True Precision barrels are known in the precision shooting community for outperforming OEM specifications. The feed ramp and chamber are optimized to eliminate reliability hiccups that can plague stock barrels, especially when you're running a variety of ammunition types.

This barrel arrives black DLC-coated, offering excellent corrosion resistance and a professional appearance. Installation is straightforward—it's a drop-in fit for the P365-FUSE platform.
