Confirmed Fitment
Star 30 Magazine Loader
The Star 30 is confirmed to fit the Super Thumb ST1, the loader ADCO builds for standard double-stack service-pistol magazines. It loads Star 30 magazines faster and with far less thumb strain — a purpose-built tool, not a one-size-fits-all compromise.
Why loading these magazines is a fight
Double-stack magazines get progressively harder to load as the spring compresses — the top few rounds are where thumbs give out. The Super Thumb pushes each round straight down against that spring tension for you, so topping off to full capacity takes seconds instead of sore thumbs.
