SIG SAUER P320-XTEN 10mm Auto Recoil Spring Assembly

SIG SAUER P320-XTEN 10mm Auto Recoil Spring Assembly

This SIG SAUER factory recoil spring assembly is an OEM replacement component for the P320-XTEN chambered in 10mm Auto. Identified by manufacturer part number 8901519, the assembly combines the guide rod and recoil spring as a matched, ready-to-install unit. It is intended for owners replacing a worn, damaged, lost, or heavily used original assembly while retaining factory-style materials and fit.

Purpose-Built for the P320-XTEN

The P320-XTEN uses a recoil system engineered around the operating requirements of the 10mm Auto cartridge and the dimensions of that pistol configuration. This assembly is cataloged specifically for the P320-XTEN 10mm model. It should not be treated as a universal P320 recoil spring or substituted into a different caliber, barrel length, slide, or compensated configuration unless SIG SAUER expressly confirms compatibility.

A properly functioning recoil assembly helps control rearward slide movement, returns the slide to battery, and supports consistent cycling. Recoil springs are wear components, so replacement can become appropriate after extended service or when inspection reveals damage, deformation, weakening, or unreliable operation attributable to the original assembly.

Factory Replacement Construction

The assembly uses steel construction and arrives as one combined recoil-spring and guide-rod unit. Purchasing the complete assembly avoids the need to source its primary components separately and helps maintain the intended relationship between spring and guide rod. Its black finish matches the appearance of the original internal component.

Included Components

• One P320-XTEN 10mm recoil spring
• One guide rod
• Factory-assembled replacement unit

Installation and Maintenance

Confirm that the pistol is completely unloaded and follow the current SIG SAUER owner’s manual when removing or installing internal components. Compare the replacement with the original assembly before use and complete all manufacturer-recommended function checks after installation. If fit, model compatibility, or safe operation is uncertain, have the work performed or inspected by a qualified armorer or gunsmith.

Keep the assembly clean and inspect it during routine maintenance for damage, binding, corrosion, or unusual wear. Replacement intervals can vary with ammunition, firing schedule, environment, and maintenance practices, so condition and function are more useful than relying on an unsupported universal round count.
