Pro-Shot 10mm/.40 Cal Pistol Brush Features The Pro-Shot 10mm/.40 Cal Pistol Brush is sized to match the bore diameter shared by 10mm and .40 S&W handguns ensuring the bronze bristles contact the rifling fully for an effective clean. The bronze bristle material is tough enough to break down carbon and copper fouling while staying gentle on the barrel s internal surfaces. A standard cleaning rod threading pattern means the brush works with the cleaning kits most shooters already own. Keeping the bore free of fouling with a properly sized brush helps preserve accuracy and reliability shot after shot. Packaged as a 12-piece bulk set this brush pack suits shooters range staff and gunsmiths who need a steady supply on hand rather than a single replacement brush. Having a dozen ready means a worn brush never interrupts a cleaning routine. Pro-Shot has built a reputation among shooters for cleaning products that perform consistently trip after trip to the range. The Pro-Shot 10mm/.40 Cal Pistol Brush 12-Pack is available for sale at GrabAGun for anyone maintaining 10mm or .40 caliber pistols.
