SMR Extended, Port-Matched Performance Barrel

$275

The SMR extended, port-matched barrel is a drop-in replacement for the SIG P365 XMacro Comp and Legion, designed to utilize the full length of the OEM slide.

With a length of 3.675 inches, it extends beyond the factory 3.1-inch barrel, increasing overall usable length within the existing slide configuration. The integrated porting is aligned with the factory slide ports to direct gases upward, contributing to reduced muzzle rise and improved shot-to-shot control.

The extended geometry and port alignment are designed to maintain reliable cycling while improving consistency during rapid fire.

This configuration provides an option for extended length and matched porting without requiring slide replacement or additional gunsmithing.
