Glad to hear your problem resolved, but still a pain on a new gun. Nobody can be happy when that happens.
I have about 56 rounds threw my new G17, but had a problem with reloads on the last 6!
Now to the real fun, - add some bullets and start shooting! I shot a box of 158 Gr. Federal Copper Jacket Solids without any malfunction in any way. Then I tried 25 of my own reloads, knowing full well that reloading is NOT APPROVED by Glock
So on two occasions, the slide would not go into battery because of my old crappy reloads. They were just round nose lead bullets, but they just did not work. Should I not have used these in a glock?
I took out the one that was so stuck that me, the range officer and an on site gun smith looked at it with the round stuck. I managed to keep pulling on it till it got unstuck.
I did however shoot most of the 300 some rounds through my Baretta PX4 with no problem inlcuding the one that was stuck in the Glock.
