Functional P320 Magazine

A short while ago I posted these photos as a tease for a P320 magazine 3D print. JP.guncad had previously dropped a P320 mag STL before he went dark, but the prints never really held up due to the extremely thin feed lips in the steel OEM magazines. After my attempts to print a plastic version of the steel P320 mags went south, I started over.

I have a polymer P320 magazine from ETS that uses different feed lip geometry to get around the problem of thin feed lips. Basically it uses an internal ramp to add some extra reinforcement that starts as a single-stack and then works its way to a double stack, just to give the polymer feed lips more bulk. I’ve run many many rounds through my ETS mag without incident, so I hoped it would work. I’m pleased to say that my printed mag based on a few specific modifications to the ETS geometry fits and feeds flawlessly.

I am going to do some work to see where I can add even more bulk to help with extra reinforcement — probably by adding layers of masking tape outside and re-inserting the magazine to figure out where it fails, then increasing the size of the model by just under that added thickness. Then I will work on a baseplate and a follower and making it functional with a Glock spring, and I’ll make it sail.

DM me if you’re interested in helping!
