Big-bore pistols and lever guns produce heavy fouling - and this .45/.40 caliber brass slotted tip gets solvent into those bores fast. It fits the .45 ACP, .40 S&W, 10mm Auto, .44 Magnum, .45 Colt, and .45-70 Government. Feed a cleaning patch through the brass slot, attach to your cleaning rod, and run it through the barrel in both directions. The slot grips the patch securely whether pushing or pulling, so you get full bore coverage with every stroke without the patch slipping off.

The .45 ACP is the highest-volume big-bore pistol round at most ranges - 200 rounds in a session is normal, and that volume leaves a thick carbon layer inside the barrel and chamber. The .44 Magnum and .45-70 add lead fouling to the mix when shooters use hard-cast bullets. Both carbon and lead need solvent contact time to break down, and a slotted tip is the tool designed for exactly that: saturating the bore with cleaner and scrubbing it back and forth to break the fouling loose before you switch to a brush.

Here's the workflow that experienced shooters use for big-bore handguns: slotted patch holder with a solvent-soaked patch for 3-4 push-pull passes, let the barrel soak five minutes, bronze brush, then dry patches on a jag to finish. Among gun cleaning accessories and rod tips, the brass slotted tip handles the messy wet work while keeping your bore safe - solid brass is softer than barrel steel and will never scratch, unlike the brittle plastic tips from box-store bore cleaning kits.
