What the Super Thumb Is — and Isn't
Super Thumb is a compact magazine-loading aid, not a bulk ammunition loader. It helps press the follower or top cartridge downward so the next cartridge can be inserted more comfortably. Compatibility should be confirmed for the customer's specific magazine.
Common Questions
Frequently Asked
Which Super Thumb fits the Glock 19?
The Super Thumb ST2 is the model identified for the Glock 19 in ADCO’s fit chart.
Does the ST2 fit every Glock 19 magazine?
Not necessarily. Aftermarket magazines, extensions, and baseplates may change fit. Confirm your exact configuration with ADCO before ordering.
Does it automatically load the whole magazine?
No. Super Thumb is a magazine-loading aid, not an automatic or bulk loader. It helps press the follower or top cartridge downward so the next round can be inserted more comfortably — you still load one round at a time.
Can it help with a new or stiff magazine?
Many shooters reach for a Super Thumb specifically because a magazine’s spring makes the last few rounds harder to press down. It provides extra leverage during loading; results depend on the individual magazine.
What if I am unsure whether it fits?
Use the Model Finder to search your exact make and model, or contact ADCO Arms directly to confirm before ordering.

Every Super Thumb loader, including the ST2, carries a lifetime warranty against defects in materials and workmanship.
