The Adco Super Thumb Loader for double stack 9mm and 40 caliber magazines takes the most tedious part of a range day and makes it painless. Anyone who has thumbed round after round into a stiff double stack magazine knows the routine, which is sore thumbs, slow progress, and less time actually shooting. This tool fixes that with nothing more than better leverage.
What the Adco Super Thumb Loader does for 9mm and 40 caliber mags
Double stack pistol magazines in these calibers are the workhorses of American shooting. They are also the magazines most people own the most of, which means loading them is a task that repeats endlessly.
The problem is not the first ten rounds, it is the last five. Spring pressure climbs steeply near full capacity, and that is where bare thumbs start losing skin.
The Adco Super Thumb Loader steps in exactly there. It gives you a broad, controlled push instead of a painful pinch, and it does that identically on magazine number one and magazine number fifteen.
Competition shooters, instructors, and anyone running a weekly practice block get the most out of it. When you fill ten or fifteen magazines before every session, a tool that shaves seconds and saves skin pays back immediately.
Features that matter on a high volume range day
A simple tool that does one job well.
- Accepts most double stack magazines in the 9mm and 40 caliber size range.
- Uses leverage to take the pain out of pressing rounds home.
- Makes reloading noticeably easier and faster than hand loading.
- Especially valuable on new magazines with stiff, unbroken in springs.
- Small enough to live in a range bag and light enough to forget it is there.
- Priced so low it belongs in every serious shooter’s kit.
Specifications and fitment
Fitment covers most double stack magazines in this size class, which takes in the overwhelming majority of duty and competition pistols chambered in 9mm and 40 caliber. That breadth is what makes it a good buy, since one tool usually covers every centerfire pistol in the safe.
There are no moving parts, no adjustments, and no consumables. Because it works purely by improving how force reaches the cartridge, there is nothing that can wear out, go out of spec, or mark up a magazine body.
An Adco Super Thumb Loader is also caliber agnostic within its size class. Whether the magazine is stacked with 9mm or 40 caliber, the tool contacts the case and the follower the same way and behaves identically.
Practical use, care, and where it shines
Seat the tool on the magazine, place a round on the stack, and press down and back in one motion. High volume practice sessions are where this matters most, when you are topping off the same mags over and over between drills.
Maintenance is a wipe with a rag when it gets dirty, and storage is wherever it fits in the bag. Grab spare magazines from our magazines and parts upgrades so you can load a full session’s worth in one sitting rather than reloading between strings.
Brand new magazines are the real test, and the Adco Super Thumb Loader handles them without complaint. Springs that have not broken in yet are the ones that shred thumbs, and this is exactly when the tool proves its worth.
Fair warning from Adco, you may need to bring extra ammo, because you will not want to stop once loading stops being a chore.
At this price, it is one of those accessories that ends up in every serious shooter’s range bag, and it makes a great small gift for the pistol shooter in your life. Buy one, use it once, and you will wonder why you spent years fighting magazine springs. Ships direct to your door, no FFL required.
