Sig Sauer P211 GTO Barrel Block Assembly - Black

Expand the competition versatility of your Sig Sauer P211 GTO pistol with the factory Sig Sauer Barrel Block Assembly in Black. Precision-engineered for 9mm Luger P211 models, this OEM conversion assembly directly replaces the factory MACH3D compensator, enabling your handgun to comply with strict match rules in competitive shooting organizations like USPSA, IPSC, and IDPA that prohibit muzzle brakes or compensators. Ideal for match division compliance as well as indoor range sessions, this barrel block maintains factory lockup and reliable cycling across a wide range of target ammunition.

Machined from high-grade steel with a durable black finish, the barrel block provides a solid, seamless aesthetic while preserving your pistol's balance and weight distribution. The kit comes complete with all required installation components, including the P211 Barrel Block, Compensator Retention Spring, Compensator Wedge Pin, Set Screw, and a dedicated 13 lb recoil spring tuned for uncompensated performance. Simple to install or swap back to the original compensator at any time, this kit ensures year-round competition readiness.
