                            This magazine is the same as a mk ii mag just with a taller follower.  I updated the spring with a tandemkross replacement and the red 11 rd follower.  Note the baseplate and plunger are identical to a current mk ii mag.

                            Perfect for my Mark 1.  Glad they had them on stock. Shipping was very quick. I received them more quickly than promised.

                            Perfect fit after follower button was swapped to correct side, which was easy after I got the instructions.

                            When I bought it I thought it was the wrong one and it turned out to be a simple fix by changing the pin to the other side. Thanks to cheaper than dirt customer  service department

                What I needed as advertised
                            
                        
                            I required a quick fix of product by changing the magazine follower button to the left side. Instructions included with purchase. Works great.

                        Does mag come with spring in it? It doesn’t look like it in picture. Thanks                    
                    
                    
                            Answer:
                            Yes. It has a spring. The Ruger Factory OEM Mark I magazines have a traditional pencil diameter spring that travels the forward channel of the mag body. It's not typically visible from the broadside view.
