Smith and Wesson Shield Magazine extension +1 and +2

thingiverse

I remixed this design from a user on Thingiverse: https://www.thingiverse.com/thing:2810236. I made some tweaks to improve its fit, and discovered that I didn't actually need the plug included in the original design. If you print this extension for use with the 7-round magazine, it will give you an extra round's capacity. If you opt for the 8-round magazine, you'll gain two additional rounds. Your choice is to use it as either an 8+1 or a 10+1 setup. To install the magazine base plate smoothly, some minor interior trimming may be required. I used a Dremel to trim it down and cleaned up the area until I make further modifications to the file.
