Back in January we shared a 3 round base pad extension for the Glock 10mm. Here is a new version that is all one piece instead of the 3 piece design from before. This one should be easier to print and overall a cleaner design. This can be modified to fit any of the Glock models and Calibers. The depth could also be modified to allow for more rounds to fit, but this might create a need for new springs which are readily available for other aftermarket extensions.
