Glock 42 Magazine Insert

Replacement for the glock 42 magazine insert. In order to change mag extensions/floorplate on the glocks, you have to press the insert down a considerable amount and apply a stern force on it to remove the mag extensions/floorplate. During this process it is possible that you can break it, as I was worried about doing to mine, so I have drawn up the file for a replacement..

Please ensure your scale is correct to be: 24.9 x 13.3098 x 3.75 mm
