Brownells Heavy Weight Brush, Nylon, 9mm/.38/.357 Cal Pistol, 12 Pack

Keeping your 9mm, .38, or .357 pistol clean means getting into the bore with a brush that actually works—and the Brownells Heavy Weight Brush, Nylon is built to cut through stubborn fouling without compromise. This 12-pack gives you plenty of brushes for your range bag, cleaning kit, and backup supply. The heavy-weight nylon bristles are aggressive enough to scrub out carbon and copper deposits that lighter brushes can't touch, yet they're safe on both rifled and smoothbore surfaces. Whether you're breaking in a new carry gun or doing serious deep-cleaning after a long range session, these brushes get the job done fast.

The brass shank and coupling are one-piece looped and wound construction—meaning no sharp edges to scratch your bore or gun parts during cleaning. The brass won't rust or corrode, and the nylon bristles won't break down when soaked in your preferred solvent. At 2 1/8 inches long with standard 8-32 male threading, they fit any rod with compatible female threads, making them a reliable upgrade or replacement brush for pistol cleaning kits across common calibers.

A quality bore brush is one of those consumables that gets overlooked until you need it—then you're stuck with whatever's in the drawer. Buy the 12-pack and you'll always have a fresh brush ready, whether you're doing routine maintenance on your daily carry or deep-cleaning after a match or hunting trip.
