MkII 22/45 Magazine Green Springs
Not that I was having any issues, but as my MKII 22/45 is about 28 years old, I figured at this price, maybe I should update my magazine springs. I have learned that lack of routine magazine maintenance, is my #1 root cause for Failure To Feed, in ANY firearm. The FTF issue is usually the result of when the fast moving bolt comes to pickup the next round, the top round has a tendency to "dip down" at the nose, and thus resulting in an FTF. To overcome this, magazines respond well to frequent cleaning, and yes even a very light lubrication on the spring and the follower are critical. I use Wilson Combat Lube. It is slick, stays put, and requires only a drop of two spread around. Fortunately Ruger MK magazines are designed where the spring puts ALL it's pressure on the nose end of the follower, so putting a strong spring in should be a plus. The new Green Springs were over an inch longer than the 28 year olds, and much more stiff, which also made them more challenging to install, as they kept wanting to snake out. I overcame this by using an actual "chop stick" as a temporary spring guide to get the spring into the magazine frame, where then I could hold it, insert the base plate plug, and slip the base plate on.

I recently purchased a used Mark 3 22/45 that was originally purchased in 2013 and the first time out with it I had at least one failure to feed out of ever magazine I ran through it so I ordered these springs to replace the old springs in all 4 of my mags and next time at the range with the new Springs installed and running the same Winchester bulk box ammo I had 0 failure to feeds out of 200-250 rounds I shot so I am very happy with my purchase!!

Needed new springs for mine and my wife’s mags. Old one were lagging and not feeding right. After a quick change change out, no more problems. They just work great!
