Had two MK III 22/45 magazines and discovered the bumper pad will not allow it to fit into a MK IV 22/45, so order new pads from Tandemkross, having never changed a bumper pad on a ruger MK magazine, I quickly discovered that the spring will shoot approximately 30+ feet, if you don't do it right, spent the next 20 minutes trying to put the damn thing back together, went to You tube and found a 3 minute video and Duh obviously I am not the first to make that mistake. 2nd magazine took about a minute to swap bumper pads. All is now good in the land of oddities.
