Confirmed Fitment
Kimber 45 single stack Magazine Loader
The Kimber 45 single stack is confirmed to fit the Super Thumb ST3, the loader ADCO builds for single-stack magazines. It loads Kimber 45 single stack magazines faster and with far less thumb strain — a purpose-built tool, not a one-size-fits-all compromise.
Why single-stack magazines pinch
Single-stack magazines have narrow feed lips and a firm spring in a thin body, so the top rounds bite back at your thumb. The Super Thumb seats each round without fighting the feed lips, which is easier on your hands and faster round after round.
