We have two Glocks. A G19, generation 2 and a G26, generation 3. Both bought used from Gander Mountain this year.
My wife and I regularly hit the indoor firing range. Last week we were there and something happened that has never happened before. Our G19 jammed two separate times. The spent shell was stuck in the slide like it didn't get ejected before the next round was chambered. To clear it, I had to actually drop the magazine, then slightly pull the slide back to get the spent shell out, as well as eject the one trying to be chambered.
My suspicion is the magazine. It happened both times on the mag that came with the gun when we bought it. The other mag we have for it is new. I've taken both magazines apart and cleaned them prior to this incident and have probably put about 500 rounds through the G19. It has never happened before this incident. It happened twice while running about 150 rounds through the gun. After I cleared it, I would reload and continue shooting with no problems.
What are your thoughts? Am I likely correct in thinking it is the older magazine? Incidentally, the mags I have are 15 rounds. This particular one says "Restricted, LE or Government use only" on it. The other 15 round mag we bough brand new doesn't say any such thing, just "9mm".
Thanks for any feedback.
