I have a Glock 43 that I've put a few hundred rounds of FMJ through with no issues. Today I tried HP ammo for the first time (Federal Hydrashock). The first round of a full mag kept getting stuck on the feed ramp when I racked the slide. Another yank on the slide fixed it every time. It happened most of the time in 2 boxes (40 rounds). It also happened once during actual firing - again yanking on the slide did the trick. But I'm shocked. I thought Glocks were supposed to be great for HP ammunition. Is this normal? I was pretty surprised to see that the feed ramp is practically vertical so I presume that has something to do with it. Also, I've never really paid any attention to the feed ramp when cleaning the gun. Do you have to do that a lot to get HPs to cycle? Thanks!
