Confirmed Fitment
Colt 22 type magazines Magazine Loader
The Colt 22 type magazines is confirmed to fit the Super Thumb STJR, the loader ADCO builds for .22-type rimfire magazines. It loads Colt 22 type magazines faster and with far less thumb strain — a purpose-built tool, not a one-size-fits-all compromise.
Why rimfire magazines are so fiddly
Rimfire magazines are notoriously finicky — tiny rounds, a stiff follower, and rims that have to sit in the right order. The Super Thumb steadies the follower and lets you drop each round in place instead of fighting the button with a fingernail.
