The Pro-Shot 10mm / .40 Calibre Nylon Bristle Pistol Bore Cleaning Brush (Model: 10NP) is a dedicated bore maintenance tool designed for handguns chambered in 10mm Auto and .40 S&W. Made in the USA, this brush utilizes extra-thick, oversized stiff nylon bristles secured within a tightly wound looped brass core and brass coupling. It enables aggressive scrubbing of carbon fouling and powder residue without scratching rifling or barrel coatings. Because nylon does not chemically react with copper-removing solvents or harsh bore cleaners, the brush prevents false-positive blue or green fouling indicators on cleaning patches while allowing bi-directional scrubbing strokes.

  • Solvent-Resistant Nylon Bristles: Heavy-duty, oversized stiff nylon fill delivers thorough bore scrubbing while remaining completely inert to harsh chemical cleaners and copper-removing solvents.
  • Brass Core and Coupling: Looped end design and brass core prevent interior barrel scratching and ensure durable bristle retention during back-and-forth passes.
  • Industry Standard Interface: Fitted with standard American #8-32 male threading for direct attachment to standard rifle and pistol cleaning rods.
  • Safe on Specialty Rifling: Suitable for treated barrel steels, sensitive coatings, and polygonal rifling profiles where wire bronze brushes are discouraged.

Who is the Proshot 10mm/40 Cal Nylon Pistol Brush for?

  • Competitive shooters maintaining IPSC Standard division handguns — requires a nylon pistol bore brush matched specifically to 10mm and .40 S&W chambers that mounts directly to standard #8-32 threaded cleaning rods and allows repeated chemical solvent application without bristling breakdown.
  • Target shooters maintaining club service pistols in 10mm or .40 S&W — needs a dedicated nylon bore brush that weighs under 15 grams to clean loose powder and carbon residue without causing mechanical wear to rifling or reacting with copper-indicating bore foam.

Less suitable for: Firearm barrels sized outside the 10mm (.400") bore threshold—such as 9mm, .357, .38, .44, or .45 calibre handguns—or cleaning rods equipped with #5-40 or #5/16-27 threads; these configurations require a dedicated calibre-specific nylon bore brush or an appropriate thread adapter.
