I started to have some issues with magazine dropping almost after each shot. I was basicly able to pull out the magazine with minimal force , without pressing the mag release.
Took the actuall mag release out and it turns out to be stamped piece of metal , pretty crappy quality. Played with it a little , took little trial and error with pliers , but think I found the sweet spot wher it holds the mag good drops it free. Considering it's such a innovative gun , that think is piece of crap. Although nice design , higher quality would made big difference
