Description

Ruger NICKEL 90231 Magazine for Mark 3, Mark  IV Standard Frame Pistols

WILL NOT FIT 22/45

This magazine will also work in Mark 2 and Mark 1 pistols, but will be more difficult to remove due to the “Butt Release” and the cleats on this magazine that are not on the 90046 and 90064 magazines.
For older Mark 1 (right hand follower button A-54 frame) you will need to swap the button to the right side.
