J. Dewey Brass Handgun Jag (Female Thread 12-28) .40/10mm

The J. Dewey Brass Handgun Jag (Female Thread 12-28) .40/10mm is a precision maintenance tool designed for operators and enthusiasts who demand a higher standard of bore cleanliness for their high-performance sidearms. When transitioning from the range to duty or defensive carry, removing carbon and copper fouling from .40 S&W, .41 Magnum, and 10mm barrels is essential for maintaining accuracy and reliable cycling. This professional-grade jag provides the necessary surface tension to ensure cleaning patches make full contact with the rifling, effectively stripping away residues that compromise ballistic performance.

Constructed from solid brass, this cleaning component features a pointed tip design that securely centers and anchors the cleaning patch during the pass through the bore. The all-brass construction is specifically chosen to be softer than barrel steel, ensuring that no damage occurs to the critical crown or lands during intensive maintenance sessions. This specific model utilizes 12/28 female threads, providing a secure and stable connection that prevents the jag from loosening while under the friction of a tight-fitting patch.

This jag is engineered for seamless integration with J. Dewey .30, .35, and .38 caliber male-threaded coated cleaning rods, making it a versatile addition to a professional armorer's kit. Whether you are maintaining a duty-issued Glock 22 or a high-velocity 10mm hunting handgun, using the correct caliber-specific jag ensures that cleaning solvents are evenly distributed and contaminants are fully extracted. For those looking to buy reliable maintenance gear, this component represents a critical investment in the longevity and operational readiness of your firearm.
