Brushing gets the fouling loose - this .357 / 9mm cotton bore mop gets it out. Run it through soaked with solvent to absorb carbon and lead residue from your handgun barrel, then follow with a dry or oiled pass to finish. Fits 9mm, .38 Special, .380 ACP, and .357 Magnum - same bore diameter, same mop.
These four calibers account for the majority of handgun ammunition sold in the US - which means a lot of dirty bores at the end of the day. Most shooters brush and patch, but skip the mop step entirely. That's a mistake. A gun cleaning mop saturated with solvent reaches fouling trapped in the bore's surface texture that a dry patch slides right over. Thirty seconds with a mop is the difference between a bore that looks clean and one that actually is.
Wash and reuse - the 100% cotton holds up well across many bore cleaning sessions before the fibers thin out. If you carry a 9mm and keep a .357 at home, this one mop covers both in your gun cleaning kit.
