Sako TRG 21 mags interchange with TRG 22

[Windrunner 50]

Hello to the Sako experts, I have some TRG 21 magazines & would like to know if they will work with a TRG 22?
Thanks in advance as I would like to give any potential buyers the correct answer.
Thanks again a d stay safe

They are nearly identical apart from the 22 mags having the nubs to grab onto and the 21 mags have a tab that sticks out off the rear of the mag at the bottom which interferes with our Catch Extender.
