Need help - Glock malfunction

**Nocaster** · 04-26-16, 18:58

Please help me with my malfunctioning gen 3 Glock 34. I bought it used on the EE here a few years back, and have put at least a very conservative 2,000 through it since. Not sure about the previous owner, but he definitely shot it a bunch. I'm not sure of the exact round count, since I usually shoot the g34 along with a few other 9 mm glocks and/or other pistols.

In the last couple shooting sessions it started having weird ejecting issues, most commonly like the one in the picture below. Before shooting today, I put in a brand new oem recoil spring. The second picture shows what the magazine looked like immediately after I stripped it after the first picture.

Sometimes the spent casing looks like a stove pipe, sometimes like the one in the picture. Also, it looks like in addition to the fresh round partially in the chamber, the next round in the magazine is partially stripped from the mag. I have no idea what this means, please help.

Which ejector does it have?

I'd start by adding a Gen4 ejector. Also clean and lube it.

Also you might replace the extractor and its spring. Problems here would result in the this type malfunction.

Thank you for the responses. I will do a detail strip and clean and replace the extractor and spring.

Okie John - I have no idea what kind of ejector, I didn't realize these were ever changed. I will look into this, too, and do some googling.

I believe all Gen3 Glock 9mms have the 336 ejector but the newer Gen4 30274 ejector is beefier and drops right into the trigger mech housing.

Thank you. I wish I knew this when I ordered lots of glock springs from Brownells last month.

Eta: ok, I looked this up and it appears my g34's R series serial number puts it within the range of gen 3s needing a new ejector and possibly extractor. I thought all my glocks were made before the problems started and I never followed the whole glock extraction saga. Now I have to check the others. ...

What kind of magazines are you using (Glock factory or aftermarket)? Have you done anything to the mags (like adding an extension or changing springs)? Is your problem happening with different magazines?

Not sure about the previous times, but during this shooting session the malfunctions happened on late model stock oem mags (the ones with the metal piece in the front). Surprisingly, my two KCI mags seem to run fine, as well as two Glock 10 rounders.
