Description
Factory Ruger 90231 10 round Magazine for Ruger Mark Series 1, 2, 3 and 4. NOT for ANY 22/45 models! WHY YES,, this WILL work in a Mark 1 or 2 it will fit in and operate just fine. If you have the pre 1972 Mark 1 just remove the button and switch it to the right side. For Mark 1 it works MUCH better than the old chrome base models and holds 10 rounds. These are new from Ruger never installed (We are a Ruger parts dealer) ***********CHECK OUR OTHER LISTINGS FOR MORE GUN STUFF***********
