The KleenBore A190 handgun bore brush is a purpose-built cleaning tool for 9mm, .357 Magnum, and .38 caliber pistols. Phosphor bronze bristles strike the right balance between cleaning power and bore safety—they're aggressive enough to scrub away fouling and powder residue without the risk of damage that harder steel brushes can cause. Whether you're maintaining a duty carry gun, competition shooter, or hunting handgun, this brush handles the job without compromising the rifling that keeps your shots accurate.
What sets the A190 apart is its construction. The bristles are straight rather than crimped, giving you more direct contact with bore walls and better scrubbing action on each stroke. The rounded bristle tips further protect against gouging, and the bristles themselves stay thick and stout—they won't bend or fold under the pressure of a proper cleaning pass. That durability means the brush will outlast cheaper alternatives and deliver consistent results across hundreds of cleaning cycles.
The 8-32" thread standard fits most standard-size bore brush handles, so you can pair this head with your existing rod or upgrade your entire setup. Made in the USA, it's the kind of straightforward, no-nonsense gun care product that works as intended and lasts.

Frequently Asked Questions
What calibers does this brush work with?
The A190 is sized for 9mm, .357 Magnum, and .38 caliber handguns. Do not use in larger caliber bores—the fit must be snug for effective cleaning.
Will phosphor bronze damage my barrel rifling?
No. Phosphor bronze is specifically chosen for bore brushes because it's softer than steel rifling. The material will clean away fouling without gouging or scarring the grooves, which is especially important for high-value firearms or precision pistols.
What handle or rod does this brush need?
The A190 features an American Standard 8-32" thread, which is the common size for handgun bore brush handles. It will fit most standard pistol cleaning rods and handles on the market. You may need to confirm thread compatibility with your current rod if it's an older or specialty product.
How long will the bristles last?
The straight, thick-bristle design is built for durability. Unlike crimped brushes, straight bristles resist bending and won't wear flat quickly. With normal use, you can expect years of service before bristle degradation becomes noticeable.
