M&P Double Stack Mag Pouch

thingiverse

I consider the design and prototyping phase of v1 completed, and expect this pouch to perform exceptionally well in practice and competition shooting. I am confident releasing the model to the community. However, I have not tested under competition conditions yet, and will continue to update and iterate as needed until completely happy with the design. I will also be adding photos and possibly videos as I continue long-term testing of the mag pouch. This mag pouch started off as a remix of user haakon1's IPSC Glock Magazine Pouch, which fits Glock 17/19/26 mags. I don't own a Glock, but looked at and tested a lot of 3D printed designs for my M&P 9mm full size because I carry 17 round magazines for USPSA competition shooting. I liked haakon1's design the best by far, but M&P mags are a little thinner than Glock mags, and I wear a 1.75 inch belt rather than the 1.5 inch belt his Glock mag pouches are designed for. Initially I imported his STLs into Blender and just stretched them to dimensions better suited for my use case, but STLs don't really play nicely in Blender, and was starting to get weird geometries as I dialed in the proper dimensions over a few print iterations. So I started from the ground up and essentially copied his design, making a few tweaks and minor simplifications as I went. The result is a mag pouch that is very strong when printed in PETG, has adjustable cant angle and tension for holding the mag in, and fits M&P double stack magazines. Am using it for 17 round 9mm mags, but as far as I know, it should work with 9mm, .40, .45 ACP and any capacity M&P magazine as long as it's double stack. It will also stay in place as tight as you like on both 1.5 inch and 1.75 inch competition belts, and has been standardized around #6-32 machine screws and nuts instead of metric, as imperial is easier and less expensive to source from my local hardware stores.
