Mark II mag in a Mark I

[elcaBob]

I have a friend who is desperately trying to find a mag for her Ruger Mark I. As I can't seem to find one, I understand that if you simply reverse the follower button on a Mark II magazine, you can use it in a Mark I.

Take a look at the following video. Start at the 2:40 mark.

Is this legit?

Thanks!

The simple answer is yes you can.

I believe it has to be the small button also.
Some of the newer MKII mags have a larger button.
