Confirmed Fitment
Colt Mustang Magazine Loader
The Colt Mustang is confirmed to fit the Super Thumb ST6, the loader ADCO builds for .380 ACP single-stack magazines. It loads Colt Mustang magazines faster and with far less thumb strain — a purpose-built tool, not a one-size-fits-all compromise.
Why .380 pocket magazines punish your fingertips
Compact .380 magazines pack a stiff spring into a short, narrow body, and the slim feed lips leave almost nothing to push against. The Super Thumb gives you the leverage the magazine itself doesn’t, seating each round cleanly without pinching a fingertip.
