The Proshot 45 Cal Nylon Pistol Brush (MPN: 45NP) is a firearm maintenance tool engineered specifically for scrubbing .45 calibre handgun barrels. Featuring heavy-duty, chemical-resistant nylon bristles wound around a solid brass core, this brush allows the safe application and agitation of aggressive bore cleaners and copper-removing solvents. Unlike traditional bronze brushes, nylon will not degrade from harsh chemicals or produce false-positive blue-green fouling stains on cleaning patches, ensuring accurate bore assessments during firearm maintenance.

Key Features

• Chemical-Resistant Bristles: Heavy-duty nylon bristles withstand strong copper-removing solvents without corroding, dissolving, or producing false fouling indicators.
• Rifling and Crown Protection: Built with soft bristles and a looped, non-pointed brass core to prevent scratching or abrasive wear on internal lands, grooves, and muzzle crowns.
• Standard Hardware Interoperability: Machined with a solid brass coupling utilizing standard American #8-32 male threads, providing direct compatibility with standard pistol cleaning rods and pull-through systems.
• Handgun-Specific Geometry: Engineered with a compact ~1.75-inch (~44.5 mm) overall length tailored for handgun and revolver barrel strokes.

Specifications

• Calibre Compatibility: .45 Calibre handguns (e.g., .45 ACP, .45 Colt)
• Thread Standard: Industry-standard #8-32 male thread
• Overall Length: ~1.75 inches (~44.5 mm)
• Bristle Material: Chemical-resistant nylon
• Core / Coupling Material: Solid brass
• Operating Type: Manual / non-powered mechanical bore brush

Who is the Proshot 45 Cal Nylon Pistol Brush for?

• .45 ACP pistol target shooters — requires a pistol bore cleaning brush sized specifically for .45 calibre bores with standard #8-32 male threads to safely apply aggressive copper solvents without causing false-positive blue staining.
• .45 Colt revolver handloaders — requires a compact 1.75-inch pistol bore cleaning brush with a looped brass core to scrub solvent through short revolver chambers and barrels without abrading rifling lands or crowns.

Less suitable for: Handguns chambered in smaller calibres such as 9mm/.357, .40/10mm, or .22, or larger calibres such as .50 cal (which require calibre-matched bore brushes), as well as .45 calibre rifles such as .45-70 Gov, where the short 1.75-inch profile is less effective than a longer 2.0-inch or greater rifle-specific bore brush.
