Sig P320 PinkyMag Extension

This pinky extension fits all compact and full-size magazines. It will not fit the subcompact magazines. You will need a very small file or pick to clean out the grooves from the supports needed to print the slots the magazine rails slide into.
The one pictured is holding up well with 75% infill during reloads where it falls directly to the ground. In the future I will go to 100% infill, this one was originally just printed for a fit test.
