Field strip your .40 S&W or 10mm Auto, drop the brass weight through the chamber, and pull. This .40 caliber bore snake scrubs and wipes the bore in a single pull-through motion. The built-in bronze brush section breaks up carbon deposits and powder residue, and the woven floss trailing behind absorbs dirty solvent and loosened fouling. Breech-to-muzzle bore cleaning in the time it takes to reload a magazine.
The .40 S&W was the standard duty cartridge for American law enforcement for over twenty years, and millions of those service pistols are still in circulation - now as personal defense and range guns. High round counts at qualification and practice sessions produce heavy carbon buildup inside the barrel and around the chamber throat. A bore snake after every range trip prevents that buildup from affecting reliability. For 10mm Auto shooters who run hotter loads, the fouling pattern shifts toward copper deposits from jacketed bullets - the bronze brush section in this bore snake addresses both carbon and copper.
Compact enough for a duty bag, a glove box, or a range bag side pocket. Machine wash or rinse with solvent when the floss darkens, air dry, and the bore snake is ready for the next gun cleaning session. It won't replace a deep clean with a rod and jag, but it handles the maintenance that keeps a .40 cal pistol running between sessions.
