PWC9 and STEN Mags (forum.guncadindex.com)

Anyone have success using sten mags printed in PLA+ ? It seems the magazine(15rd lower) cant firmly hold multiple rounds without rounds just popping off the magazine. Im guessing 100% printed magazines arent ideal. Maybe I should try STEN mags but with the RR metal inserts.

Thoughts ?

I used those magazines in another project, the printed ones failed before two full mags. The ones with metal feed lips lasted quite a while, even left loaded in climate controlled area. They only met their demise when I forgot they were in the hot car.

yeah... i actually had cycling success when at first with the fully printed mag. then it started to not hold onto rounds.. like in your pic.. the round would just end up in weird places in the upper.
