I not sure what is going on here. Would appreciate some input.
I was at the range with my Glock 23 (.40). I had 50 rounds of Federal Hydro Shok that I fired without any problem what so ever using three different mags.
Then I started to go through the 100 rounds of Winchester white box and I began to have problems. I loaded 5 rounds into the mag and I would fire the first two and then it would fail to feed the third round, leaving the slide open. A quick tug on the slide cured the problem and the remaining 3 rounds fired fine.
Thing is this problem continued for the entire 100 rounds always failing to feed the third round. I rotated through all the mags with no luck.
I have approx 800 to 1000 rounds through the Glock with no problems before this. I think that this is the first time I've run Winchester through it, but I'm not sure. Either way, this doesn't seem like an ammo problem to me... or am I mistaken?
BTW all the mags are "Glock" and I've not made any modifications to the gun. It's factory stock.
