After the bore brush scrubs out carbon and lead fouling, this .40 caliber cotton bore mop carries it out of the barrel. Fits both .40 S&W and 10mm bores - same diameter, one mop. The densely packed 100% cotton head absorbs solvent along with the residue it loosens, giving you a cleaner bore in fewer passes than patches alone.
The .40 caliber runs at higher pressures than 9mm, which translates to more carbon fouling per round. Duty shooters and competitors who put serious volume through a .40 know the drill: brush, then mop with solvent, then mop with oil. Skipping the gun cleaning mop step means residue stays trapped in the bore's surface texture - solvent loosens it, but something has to absorb and remove it.
100% cotton - wash and reuse through multiple bore cleaning sessions until the fibers thin out. This pistol cleaning mop is one of the simplest steps you can add to your routine - and one of the most effective at keeping your .40 running clean.
