First of all I would like to say anybody who goes out and sells their legion pistol because of this video is an idiot. Sorry to come across like a jerk but I really feel that way. We have yet to see the longevity of this Arex brand but all reviews are very positive so time will tell. These experiments are to be taken with a grain of salt, however you cannot deny the impressive performance the Arex gave through this test. MAC is supposed to conduct this experiment on all the most popular pistols and I'm really wondering if any will do as well as that Zero 1S did that particular day. My sig p320c also failed his experiment and I haven't lost any confidence in it as its still heavy in my carry rotation. Don't be so defensive over the sig that you don't give credit where it is do. As far as the whole tighter tolerances theory goes it would be feasible if it were actually true. MAC explained that he actually believed the Arex to be the tighter gun on his Facebook. Plus the fact sig is not marketing the legion as some tight tolerance and break in needed competition pistol, but rather an operator pistol. So guys just stop with the excuses (wrong lubricant, tight tolerances, American sig quality, break in needed). Don't worry I think many other of our beloved guns will fail this very same experiment. I'm rooting for the ppq and Cz p01 to kick butt in this test.
