Well, I clean and lubed, checked everything I could but she still jams. I was able to get two mags through but then by the 3rd mag, it double feeds. Well, what it does is fails to eject the spent cartridge and as it tries to feed the fresh one, pushes the spent cartridge up against the ejector. Definitely not the right direction and it jams in there pretty good. Sigh. I wanted to like the gun but this is not quality control. The mags sucked out of the box, It has this issue. Lets see if I have to jump through hoops to get it fixed.
