Pro-Shot Patriot Series HD Nylon Bore Brush | .38 Cal / 9mm Pistol PSP38/9

Standard brushes often leave you guessing if that blue patch is copper fouling or just the brush itself breaking down. The Pro-Shot Patriot Series HD Nylon Bore Brush solves this by providing a heavy-duty, non-metallic scrubbing surface for your .38 or 9mm pistol. Engineered to remove stubborn carbon without the risk of "false-positive" copper readings, this brush gives you an accurate look at your barrel’s cleanliness while protecting delicate, match-grade rifling.

The real edge here is how these materials handle aggressive chemicals. Unlike bronze, these high-density nylon bristles are completely inert to ammonia-based solvents, meaning they won’t degrade or skew your results during a deep clean. We’ve built these bristles onto a solid brass core with a looped-end design, ensuring the brush stays rigid and stays together. This setup maintains constant contact with the lands and grooves without the "spring-back" spray common with cheaper synthetic brushes.

By pairing a stiff nylon filament with a reinforced brass core, this brush delivers the scrubbing power needed for .38 and 9mm caliber tolerances. The design eliminates the flex that leads to inconsistent cleaning, allowing you to focus on carbon removal without worrying about crown damage or solvent splash-back. It’s a professional-grade tool that lets you accurately assess your bore's condition while providing a safer, more effective cleaning cycle.

Features

• High-density nylon bristles with increased filament stiffness and packing density for continuous bore contact and improved carbon fouling removal
• Non-metallic bristle composition with no copper or bronze content, ensuring accurate patch readings when using ammonia-based solvents
• Solid brass core providing higher torsional rigidity under load, resulting in reduced flex and more controlled stroke alignment
• Looped-end construction with enclosed tip geometry to minimize the risk of crown damage during insertion and extraction
