Just got to shoot my 17 3rd gen this last sunday. Put about 150 rounds through it. First glock ive shot. Last pistol i owned before this was the sigma so you can imagine how happy i am with the purchase of this glock. My only concern is that i had one failure to eject. I bought the glock used but because of the condition it is in, im pretty sure there has been less than 1000 rounds through it. Is a failure to eject common on a glock this new?
