How do you tune a Glock extractor? My G19 extracts just fine, but seems to like to ping me in the forehead sometimes. My G26 and G17 do not have this problem. I did a google search for this problem and found a lot of the same complaints but no solutions, except the Cylinder and Slide website listed a custom glock for sale with a radiused and tensioned extractor. Does anyone know exactly how this is done?

Bend that factory one @ your own risk. I'd be more inclined to start with a different rate spring, it's easier to do and reverse if it's fu**ed up. Shaping and bending is irreversible. You could always buy another 1, but I'd avoid that of course.

I was having this same problem of erratic ejection in one of my two 3rd Gen G19s. It was happening with all my ammo, from anemic bulk pack 115 grain stuff to 124 gr NATO stuff to 147 gr FMJ and JHPs. About a third of the time the fired case would land about 3-5' to the shooter's right rear, about a third of the time over the shooter's head (or into his forehead), and a third of the time straight up in the air or forward.

It was happening across a number of shooting sessions, when I was shooting and when I had a friend who is a nationally-known firearms instructor shoot it. We had a couple of spare ejectors on hand, so we dremeled a bit (only about .013") off the tip of the ejector in the gun. Immediately we went out again and tried about 5-10 rds of each ammo type that had previously shown the erratic ejection. The problem was now gone. With all the types of ammo the gun was now consistently depositing its fired cases to the shooter's right rear. We both shot the gun and both experienced the improvement.

My belief is that this was a case of tolerance stacking, that the unique combination of dimensions of slide, extractor, frame, trigger housing, and ejector in this particular gun had added up to cause the problem.
