Confirmed Fitment
Colt 1911 equivalents Magazine Loader
The Colt 1911 equivalents is confirmed to fit the Super Thumb ST1, the loader ADCO builds for standard double-stack service-pistol magazines. It loads Colt 1911 equivalents 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.
