I just got one of these, Serial EAT20xx. Fired 100 rounds at the range and found a problem. The last round in the magazine will not always feed properly into chamber, it will keep the slide slightly open, forcing me to eject it. This happened on 3 different magazines and it doesn't matter how many bullets are in magazine to start with; its always the last shot, or if you load the magazine with one bullet.

Anyone have this issue? I took it back to the dealer, they said clean it and fire another 100.
