The Fiocchi ammo really gave me headaches... thought it was the gun and did extensive testing and polishing the chamber trying to stop the jams. I finally checked the ammo and found that the case mouths were the problem with the Fiocchi ammo. I think I had bought a case of 170-grain FMJ. It worked fine in my Glock 23C. Anyhow, the case mouths are thicker and more pronounced, causing them to catch at the top of the chamber, but taking the tiniest bit off pressure off the recoil spring by pulling back ever so slightly on the slide would allow the round to fall down and chamber without assistance.
