SIG P211 Barrel Block

Description

Reduce front-end weight and fine-tune the balance of your P211 with this lightweight P211 barrel block, precision-machined from hard-coated aluminum for durability and long-term wear resistance.

Designed as a replacement for SIG’s Mach3D Compensator, it gives the pistol a lighter, faster-handling feel that can help improve transitions and overall responsiveness—a clean, purpose-built option for shooters who want a more streamlined competition setup.

Our team has designed this Grayguns barrel block for your SIG P211 to be more functional, easier to install and easier to maintain. It features improved mounting hardware, including an oversized countersunk set screw with more than twice the thread engagement of the OEM version.

Grayguns guarantees the P211 Barrel Block for life, just like all Grayguns components.

P211 Barrel Block Fit Guide

The barrel block is designed specifically to replace the compensator on your P211-GTO Competition pistol.

The P211-GT4 and P211-GT5 do not feature the Mach3D Compensator. This assembly is not compatible with the GT4 or GT5.

SIG P211 in USPSA, IDPA, and IPSC

With the barrel block, you do lose the advantage of having a compensator. Still, the assembly allows you to shoot your P211-GTO in divisions that exclude compensators. (Double check weight limits!)

The strong, lightweight materials are one piece of the puzzle to help competitive shooters meet competition weight requirements.

Match rules for the International Defensive Pistol Association® (IDPA) Enhanced Service Pistol (ESP) Division limit the weight of the unloaded firearm. The limit is 43 ounces or less.

• Our P211 GTO Aluminum Magwell reduces the weight of the gun by 1.2 ounces.
• Our barrel block reduces the weight of the gun by .79 ounces.

Using both Grayguns components will get your gun down from about 45.66 ounces to 43.67 ounces. (We’re getting closer!) Weights are for informational purposes only. We suggest you weigh your own pistol as weights may vary.
