Hoppes Cleaning Patches No. 4 .38-.45/40

Hoppes Cleaning Patches No. 4 .38-.45/40 are purpose-designed cotton patches sized for medium to large caliber handguns and rifles. These patches fit standard cleaning rod jags for .38 Special, .40 S&W, .45 ACP, and .40 caliber firearms, making them a field-proven essential for operators maintaining weapons across common duty and training platforms. The No. 4 size bridges the gap between smaller calibers and larger rifle bores, offering versatility in any serious shooter's maintenance kit.

Cotton construction ensures effective solvent absorption and carbon removal without leaving lint or fibers in the barrel. The appropriate patch diameter for these calibers means efficient contact with bore walls during the cleaning stroke—critical for removing fouling and copper buildup that accumulates during high-round-count training or duty use. Hoppes patches are a standard reference in law enforcement and military armorer protocols for routine bore maintenance, trusted for their consistent weave and durability across multiple cleaning cycles.

This product serves patrol officers, competitive shooters, military personnel, and range facilities that maintain inventories of mixed-caliber firearms. Whether running qualification drills on duty weapons or deep-cleaning after live-fire training, the No. 4 patch size handles the workload across your handgun battery without requiring multiple patch types. Individual operators and armory personnel stock these in bulk because they're consumable, reliable, and compatible with any standard three-piece rod system used in the field.
