Just added a Gen 4 G26 and a Gen 4 G19 to go with my Gen 3 G34. I took them all to the range yesterday and put about 200 rounds through each of them without any issues I'm happy to report. The 19 ejected each shell at 4:00 like it should about 5 feet away. No FTE, stove pipes, or brass hitting me in the face. Both the Gen 4's test fire date was February of 2012. I was using cheap Wally World Federal ammo so I wasn't using high powered rounds. I was somewhat apprehensive with all the reports of ejection issues. All three of my Glocks so far have been flawless so far like they should be. I know everyone likes pictures so I have one attached I hope it attaches alright it's the first time I've tried to attach a picture to this site. The G26 took a little time to figure out the small sized grip but the 19 was really awesome to shoot. I wish I would have waited for the Gen 4 G34 to come out before I bought the Gen 3 but hindsight is always 20/20.
