M&P 9 Mag extension (no extra capacity

thingiverse

These replace the base pad on the Canada legal 10 round magazines. It makes them longer so they're easier to get out of mag pouches and I found the factory ones had a rim on the base that pinched my hand. There are 5 files, one without a number and then four numbered one through four so you can keep track of your magazines and see which ones give you grief.
