The 610 Cleaning System is specifically designed to clean .22-.45 caliber pistols. Now automatics can be cleaned correctly, from Breach to Muzzle without disassembly. 3", 100% cotton, all-caliber patches and a heavy-duty bore brush easily strip the copper and lead from bores. This pistol cleaning system comes with a .20 caliber & a .30 caliber solid brass slotted tip,  a .20 caliber & a .30 caliber obstruction remover, which can be used to clean obstructions out of the bore, a t-handle bar for added comfort while pulling the flexible rod through the barrel, and a bore reflector/flag safety. This kit would not be complete without the .5oz tube of Otis O85 Ultra Bore Solvent, and the .38 & .45 caliber bore brushes. Everything is neatly packed in a .5lb pocket size, softpack case complete with a belt loop attachment and a locking zipper.
