Strike Industries Micro Threaded Barrel Comp CIRCLE, 1/2x28, 9mm/.357 SIG, QPQ Black

The Strike Industries Micro Threaded Comp CIRCLE is a minimalist compensator designed for micro, sub-compact, compact, and full-size pistols with 1/2x28 threaded barrels. At just 0.64 inches long, it redirects propellant gas to reduce felt recoil by approximately 8 to 15 percent while controlling muzzle rise. The QPQ black finish provides corrosion resistance, and the O-ring assisted retention system ensures reliable timing. This compensator also functions as a compact thread protector when not actively compensating, making it a versatile addition to any threaded barrel pistol.

Key Features

• CIRCLE design with gas redirection ports for recoil and muzzle rise reduction
• O-ring assisted timing and retention system with three replacement O-rings included
• Micro profile at 0.64 inches maintains holster compatibility with most existing setups
• QPQ black finish on AISI 1144 steel resists corrosion and wear
• Dual function as both compensator and compact thread protector
• Compatible with 9mm and .357 SIG calibers on 1/2x28 threaded barrels

Perfect For

• Shooters running micro, sub-compact, and compact pistols with threaded barrels
• Concealed carry setups prioritizing minimal profile and holster fit
• Competitive shooters seeking muzzle control without bulk
• Owners of full-size pistols wanting lightweight recoil management
• Anyone needing a compact thread protector with active compensation benefits

Compact Design Meets Performance

The CIRCLE design uses strategically positioned gas ports to redirect propellant gases, reducing felt recoil and muzzle rise without adding significant length or weight. The minimalist 0.64-inch profile keeps the compensator compact enough to work with most existing holsters, making it practical for both duty and carry applications. The O-ring retention system ensures consistent timing between shots, and the included three spare O-rings allow for easy maintenance and tuning as needed.

O-Ring Timing and Tuning Considerations

The O-ring assisted retention method requires proper barrel shoulder engagement for reliable timing. Threaded barrels without a shoulder may not work as intended with this compensator. Recoil spring tuning may be necessary depending on your specific firearm and ammunition combination. Strike Industries provides detailed installation and maintenance instructions to help you dial in the optimal setup for your pistol.

Material and Durability

Machined from AISI 1144 steel and finished with the QPQ process, this compensator resists corrosion and maintains its black finish through extended use. The bead blasted surface preparation provides a professional appearance while the QPQ coating ensures long-term durability in various shooting conditions. The minimal weight of 0.35 ounces means virtually no impact on your pistol's balance or handling characteristics.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Verify barrel thread pitch and shoulder engagement before installation. Recoil spring tuning may be required depending on firearm and ammunition combination.
