The Hoppe’s 9 Nylon Pistol Bore Brush (Model HP1308) is a dedicated firearm maintenance accessory engineered for the routine care of large-bore handguns. It is designed to safely and effectively scrub away loose powder residue, carbon, and light fouling from inside the barrel. Featuring high-durability Tynex nylon bristles wound around a sturdy coiled core, this brush provides a thorough mechanical cleaning action without scratching the bore. Lightweight and compact, it weighs approximately 0.06 lbs (27 grams) in its packaging, with package dimensions of approximately 5.00 x 1.75 x 0.50 cm.

Key Features

• Chemically Inert Bristles: The nylon bristles are completely resistant to aggressive chemical solvents, including ammonia-based copper cutters and CLP formulas, meaning they will not degrade or produce false-blue copper indications during cleaning.
• Shape Memory: Built with high-quality Tynex nylon, the bristles possess a built-in memory that allows them to flex during the cleaning stroke and immediately return to their original straight shape, preventing matting or flattening.
• Multi-Directional Scrubbing: The spiral-wound bristle design provides multi-directional contact inside the barrel rifling to deep-clean grooves and lands.
• Standard Threading: Equipped with a standard 8-32 male thread, allowing direct compatibility with standard Hoppe's cleaning rods and most universal cleaning rods.

Who is the Hoppes Bore Brush Nylon Pistol .45 for?

• Handgun owners maintaining large-bore sidearms — requires a bore cleaning tool specifically sized for .44 and .45 calibre barrels, ensuring this nylon pistol bore brush makes optimal surface contact with the rifling to lift carbon and powder residue.
• Shooters using aggressive ammonia-based copper solvents — benefits from a chemically inert nylon pistol bore brush that will not dissolve, degrade, or produce false-blue copper readings when exposed to harsh solvents, utilizing its standard 8-32 male thread to attach securely to standard cleaning rods.

Less suitable for: firearm barrels that are still hot from shooting and exceed 220°C (428°F) where nylon bristles risk melting, rifle-length barrels of the same calibre that require a longer rifle-length bore brush to maximize surface contact, or firearms with heavy, baked-on copper jacket fouling which require a highly abrasive phosphor bronze bore brush for mechanical removal.
