Keeping your 10mm, .40, or .41 caliber handgun clean starts with the right bore brush—and the KleenBore A191 phosphor bronze bore brush is built specifically for those calibers. This isn't a one-size-fits-all brush adapted from rifle stock; it's engineered for the bore dimensions and rifling geometry of mid-sized pistol cartridges, which means more effective fouling removal without the risk of damage that comes from oversized or undersized cleaning tools.
The A191 uses phosphor bronze bristles—the smart choice for handgun cleaning. Bronze won't harm or enlarge the grooves in your barrel the way steel bristles can, and the straight (not crimped) wire design gives you genuine cleaning power where you need it. The bristles are tapered with rounded tips, so they scrub away powder residue and copper fouling efficiently without gouging the bore surface. The brush itself stays stout and rigid; it won't collapse or bend under normal cleaning pressure, so you get consistent scrubbing action from chamber to muzzle.
Built to US standards with 8-32" threads, this brush fits standard-sized cleaning rod adapters—the same threading you'll find on Kleen-Bore and most other quality rod systems. It's made in the USA, which means it's held to the material and manufacturing tolerances that matter when you're protecting your firearm's internals. Whether you're running through a quick post-range cleaning or tackling buildup from heavy practice sessions, the A191 delivers the brush quality that serious shooters depend on.

Frequently Asked Questions
Will this bore brush fit my cleaning rod?
The A191 features an 8-32" thread, which is the American standard size used by most quality cleaning rod systems, including other Kleen-Bore products. Check your rod's adapter to confirm it accepts 8-32" threads.
Why phosphor bronze instead of steel?
Phosphor bronze is softer than steel, so it cleans fouling and powder residue effectively without the risk of enlarging or damaging your barrel's rifling. Steel bristles can gradually wear grooves wider, especially over many cleaning sessions. Bronze protects your bore while delivering the scrubbing power you need.
Can I use this brush on all three calibers—10mm, .40, and .41?
Yes. The A191 is designed for all three calibers. These three cartridges share compatible bore diameters, so a single brush works across all of them.
What's included in the package?
You receive the A191 bore brush with 8-32" threads. It does not include a cleaning rod or rod adapter; those are purchased separately.
