Ruger Mk 11 magazines

[herky]

Are Ruger Mk 11 magazines the same as the Mk 111?    Question is will the Mk 111 work in a Mk 11 pistol?

No, the mag release on a MkII is a heal release and the MkIII is a thumb release ala 1911.

I use MkIII magazines in two Ruger Standard Pistols (pre-MkI). a MkI, and even in a .22/45 (with the basepad changed). Never had an issue. The only caveat is that when pulling them out, you need to push slightly to the rear on the base so the MkIII mag catch notch/protrusion doesn't hang up on the lower edge of the grip frame.

 

In the Standard Automatic Pistols with the earlier frames,  you have to move the follower button to the opposite side of the magazine tube, but it seems to work fine. 

 

You probably can't use MkI, MkII magazines in a MkIII pistol due to the MkIII mag catch notch/protrusion not being on the MkI & MkII magazines. They'd probably work, but won't lock into the gun.

 

Best way to be sure is try it yourself. Buy or borrow one MkIII magazine and see if it works with your MkII.
