Birchwood Casey Brass Push Jag - .357/.38 Caliber & 9mm Gun Cleaning Tool

Keeping your handgun barrels clean is the foundation of reliable performance and longevity, and the Birchwood Casey Brass Push Jag makes the job straightforward. This brass jag is purpose-built for .357, .38, and 9mm calibers, fitting standard cleaning rod setups so you can efficiently remove fouling and buildup from your bore. Whether you're a revolver enthusiast, semi-auto shooter, or someone who runs multiple handgun platforms, having a caliber-specific jag ensures you're not forcing the wrong tool down your barrel.

Brass construction strikes the ideal balance for gun cleaning—it's soft enough to prevent damage to your barrel's rifling while remaining durable enough for regular use. The push jag design works with conventional rod-and-patch setups, letting you run patches through in either direction without snagging or binding. It's a straightforward, no-fuss piece of kit that belongs in every shooter's cleaning kit.

If you shoot .357 magnum, .38 special, or 9mm regularly, a caliber-matched jag saves time and reduces the risk of using an oversized or undersized tool that can slip or cause uneven cleaning. Birchwood Casey's jags are a trusted standard in gun maintenance shops and at home benches across the country.
