re: My new Glock 19 jams a bunch

I see a couple problems here. And while I am genuinely trying to help, gaining a little knowledge can't hurt. First off...the Glock does not have clips. It has magazines and secondly your magazines fit fine. Also a Glock 17 is a full size pistol. The subcompact Glock 9mm is the 26. Glock numbers their pistols according go the ordered number of it's patents. But the Glock 17 is larger than your 19 and there is nothing small about it.

Now as for the jams, what kind are they? Failure to feed (ftf), failure to eject (fte), stove pipe, double feed? 90%+ of all stoppages are magazine related. All of my mags have a number on them so that I can keep track if I have any problems. Put a piece of masking tape on the bottom of your mags and pay attention to which one(s) are jamming. If it is a failure to extract you cab cheaply purchase a new extractor.

Lastly if you were shooting reloads try some factory ammo. Maybe the load in the reloads wasn't hit enough. If all thus fails contact Glock or find a smith.
