Sorry so late, busy with work. still haven't called the number. to put more light on the subject, i tried it with 16, 15, 10 and Zero in the mags, still have to physically reach up and pull (tug) the magazine out of the well. i figured "well it just needs broken in" so i did a few HUNDRED mag changes, and nothing. i'm to the point where i am seriously considering breaking out some 250grit emery cloth, but that would constitute "Modification" and void any expressed/implied warranty. so- will call the number and report back with results, if any.
It should be noted that despite the issues stated above, this new brother to my P01 shoots excellently and i have experienced ZERO malfunctions so far, logged 75 rounds so far

MAN work sucks! stoopid airplanes....
