Otis FG645 Professional Pistol Cleaning System (.22-.45 Cal) with Black Compact Soft Pack Case

The Otis FG645 Professional Pistol Cleaning System is a complete pistol cleaning kit engineered for shooters who maintain handguns from .22 to .45 caliber. Built around Otis Technology's field-proven Memory Flex cable and backed by a thoughtful array of proven cleaning tools, this system handles everything from routine range sessions to deep maintenance of your entire handgun collection—all organized in a compact black soft pack case that stays ready to go.

What sets this kit apart is the intelligent design: the Memory Flex cable doesn't kink or tangle, patches can be repositioned across six cleaning passes for efficiency, and every tool has its own slot so nothing gets lost. Whether you're running a 9mm carry gun, a .40 duty pistol, or a .45 ACP for hunting or tactical work, you've got the right bronze bore brushes, brass slotted tips, and cleaning fluids on hand. The included Otis O85 Ultra Bore cleaner, lubricant, and protectant in one handles the chemistry; the fiber optic bore reflector and safety flag let you verify your work and keep safety top of mind.

Compact enough to stash in a range bag or truck, sturdy enough to last years of regular use, and organized enough that you'll actually find what you need in the moment—that's the Otis approach to handgun maintenance. The zippered case includes a 2½-inch belt loop, so you can secure it wherever you store your gear.
