Custom Tuned 15LB Recoil System

For AXG Legion, Radian RAMJET & Premium 3.7" P365 Builds

A premium captured recoil system selected by Heritage for compensated, ported, and gas-driven 3.7" SIG P365 XL / XMACRO performance platforms.

Tuned for the Builds That Need It Most

The Heritage Custom Tuned Recoil System was selected for our premium 3.7" P365 performance builds, including the AXG Legion, Radian RAMJET + AFTERBURNER, and upcoming FDEZ Werx compensated and ported slide packages.

Compensators and ported slides use escaping gas to reduce muzzle rise and soften recoil. That gas management can change the way the slide cycles. A properly selected recoil spring can help the platform feel smoother, track flatter, and cycle more consistently with the right ammunition.

Why Heritage Chose 15LB

This 15LB configuration is lighter than the common factory-equivalent recoil spring setup, making it a strong performance choice for many compensated and ported 3.7" P365 builds.

It is our preferred balance point for the platforms we specialize in: premium AXG Legion builds, Radian RAMJET slide packages, and custom ported or comped P365 XL / XMACRO configurations.

Heritage Performance Note

This is the recoil setup we prefer for many of our premium compensated and ported 3.7" P365 builds. It was chosen to complement platforms where gas is being redirected for recoil reduction, including AXG Legion, Radian RAMJET, and FDEZ Werx performance slide configurations.

As with any recoil tuning, performance can vary based on ammunition, slide weight, optic weight, compensator design, porting, maintenance, and break-in. Always test your firearm with your chosen ammunition before relying on any defensive or competition setup.
