Description
There's a reason Hoppe's has been the name people reach for when it comes to gun care for over a century, and the PCO38B is a great little snapshot of why. This kit pulls together the essentials for cleaning a .38, .357, or 9mm pistol into one grab-and-go package, so you're not hunting around for the right brush or scrounging for a rod at the range. It's the kind of thing that lives in a range bag or a nightstand drawer and just quietly does its job.
What Comes in the PCO38B Kit
Inside you'll find a 2 oz bottle of Hoppe's No. 9 Gun Bore Cleaner, which cuts through powder, lead, metal fouling, and rust, along with a 2.25 oz bottle of lubricating oil that stays put and won't gum up or harden over time. The kit also includes a one-piece aluminum cleaning rod, caliber-specific bore brush, slotted ends and adapters, round cotton patches, and cleaning instructions. It's a complete loop from scrubbing the bore to wiping down and oiling the moving parts.
Cleaning a .38, .357, or 9mm with the PCO38B
One rod covers all three calibers since they share a similar bore diameter, which is part of what makes this kit so handy for anyone running a revolver and a 9mm semi-auto out of the same bag. Run a solvent-soaked patch through the bore, follow with the brush, push clean patches until they come out dry, then hit the slide rails and contact points with a touch of oil. First-time gun owners tend to like this kit because it doesn't overcomplicate a simple job, and seasoned folks keep one around because the No. 9 formula just works.
Built for the Range Bag
The whole thing tucks into a reusable clamshell case that's easy to toss in a bag or stash on a shelf. Nothing fancy here, just a dependable, no-nonsense kit from a brand that's been doing this longer than most. If you own a handgun in these calibers, it's tough to go wrong keeping one on hand.

Frequently Asked Questions
Does the PCO38B kit really work for all three calibers?
Yes, the kit is designed for .38, .357, and 9mm pistols, which all share a close enough bore diameter to use the same rod and brush. That makes it a convenient single kit if you own a revolver and a 9mm semi-auto. Some owners also use it on .380 handguns for the same reason.
Is this a good cleaning kit for a first-time gun owner?
It's one of the more beginner-friendly kits out there. It includes everything needed for a basic clean without a bunch of parts you won't use, and it comes with instructions to walk you through the process. The proven Hoppe's No. 9 solvent does most of the heavy lifting.
What does the Hoppe's No. 9 solvent in this kit remove?
The No. 9 Gun Bore Cleaner tackles powder residue, lead, copper and metal fouling, and helps guard against rust. It's the same formula Hoppe's has been refining for well over a hundred years. The included lubricating oil then protects and smooths the moving parts after cleaning.
Will the cleaning rod fit in a range bag?
It will. The one-piece aluminum rod and all the accessories pack down into a compact clamshell case that's easy to toss in a range bag or store in a drawer. It's built to travel, so you can keep it wherever you do most of your cleaning.
