Best Modification for Ruger Mark IV 22/45
I have an original Ruger "Mark II" 22/45, and recently bought the "Mark IV" and found with this simple change, I can use the "Mark II" magazines in the "Mark IV." I will eventually get these for the rest of my magazines.

Great addition to your magazines
Love these bumpers. They give you a spot to hit with your palm to confirm your magazine is fully inserted. Good quality too.

Mags
Fast shipping easy to use fit perfectly

Perfect Fit!
Install can be a little fidgety with the smaller magazine compared to say a 9mm base.
