Quoted:
I'd agree with the above post to have someone else shoot it, but if you are familiar with shooting Glocks and the brass is still ejecting poorly, then I'd bet it is the gun and not you. Shouldn't matter if the ammo is +P or not, it should run.
I had the same problem with a NIB 3rd Gen G19 I bought a couple years ago, VERY poor ejection. I was getting cases dribbling out of the ejection port, ejecting to the front of the gun, cases hitting me in the head and even a few ejecting to the left of the gun, in addition to ejecting from about 2:00-6:00 o'clock. Absolutely no consistency to it, either, even with +P ammo.
The gun had the old 336 ejector installed, so I called Glock and told them what was going on. The tech really didn't even quibble, he told me to contact an armorer and they would ship out the new 30274 ejector. I told him I was an armorer and, after confirming, they shipped it out. The ejector arrived about a week later and it was a simple job to switch them out.
Took it back to the range and it was MUCH better. No more brass to the head and face, no more ejecting to the left, no more ejecting to the front of the gun. All went to the right, some further than others, but all to the right. Ejection wasn't as consistent as my old G26 or my old, 1st Gen G17, but MUCH better; good enough that, when I go out to qualify at my PD job again, I'm going to qualify with and carry the G19 as my duty gun.
Pics of the ejectors so you can ID which is in yours:

336 ejector installed. It will have "336" stamped on it and is a lot more pointed. It will bend to the right some when viewed from the top.

30274 ejector installed. It is a lot more blunt and is twisted- the top bends to the right, but the bottom is almost straight. Should have "30274" stamped on it.
If you have a 336 ejector, your best bet is to see if you have an armorer nearby. If you can find one, the armorer can order the 30274 ejector and switch it out for you, often free of charge or for a very minimal fee. Second choice would be to call Glock and arrange to send it in for the work. Bad news is that they will refuse to pay shipping, so you are looking at about $80.00 for overnight shipping. This really isn't anything new, as far as I know Glock has always refused to pay shipping, except in certain very narrow circumstances. Sucks, but it is their corporate policy. If you are mechanically inclined, you can order a 30274 ejector from any of the various places selling Glock parts and install it yourself. It really is pretty easy, but if you are the type that can screw up boiling water, best to leave it to someone else.
The 30274 usually works for erratic ejection, but sometimes it is still present. If it doesn't work for you, call Glock. I don't know if it was for LE only, but at one time, if you had a 9mm Glock that the 30274 didn't solve ejection problems on, they would offer you a new Gen4 gun, provided you shipped your gun to Glock. I don't know if they still do this, and like I said I don't know if it is for LE only but it is worth a try if the 30274 doesn't solve your problems. Good luck. I wish to hell that Glock would take care of these problems, but they seem to have the attitude that it isn't a widespread problem, so they won't address it.
