Sig Sauer P365-XMACRO Comp OWB Holster (MACRO)

Sig Sauer P365-XMACRO COMP OWB Holster

The Sig Sauer P365-XMACRO COMP OWB Holster from Four Brothers Inc. is designed for secure Outside Waistband carry with reliable retention and durable construction. Precision-molded specifically for the Sig Sauer P365-XMACRO COMP, this holster provides a stable, accessible platform for range use, training, and everyday OWB carry.

This holster is also compatible with the Sig Sauer P365-XMACRO, P365-XMACRO TACOPS, and P365-XMACRO COMP ROMEOZERO ELITE pistols. Models equipped with a manual safety are fully supported.

Each holster is vacuum-formed using a precision-machined mold developed from CAD models of the actual firearm. Every holster is formed, trimmed, and assembled in-house, then tested with real pistols to ensure consistent retention and proper draw performance.

Designed for Reliable OWB Carry

The OWB configuration provides a comfortable and stable carry platform while maintaining quick access to your firearm. Adjustable retention allows users to fine-tune the draw resistance to their preferred level.

The holster profile is cut to accommodate most slide-mounted red dot optics commonly used on the P365-XMACRO platform. The open muzzle design also supports threaded barrels or compensators that extend beyond the slide.
