Today I took my G43 to the range. The gun is less than a year old and had only 383 rounds through it when I got to the range. I shot up the 124 gr Gold Dots that I keep in the pistol and then switched to 124 gr American Eagle or 115 gr. Aguila. (I'm not sure which. I shot some of both this afternoon.) After I'd put a few mags of range ammo through the pistol, the gun the gun failed to fully return to battery during the middle of a mag. I tapped on the back of the slide and it still didn't return to battery. Then I tapped the back of the slide a bit harder and nothing changed. I removed the mag, and ran the slide by hand to eject the round in the chamber. When the slide went forward on an empty chamber, the gun still didn't return to battery. I cycled the slide again and that time the gun went into battery. Then I removed the slide and lubed the rails.
I shot another ~80 rounds. Again the gun failed to go into battery, and tapping the back of the slide wasn't enough to fix it. The slide was almost all the way forward. It stops right before or maybe during the vertical travel of the rear of the barrel during locking. It's almost like the slide is binding on something or like there something interfering with travel of the barrel lug over the locking block.
I've done nothing to the gun besides clean it. I haven't replaced any parts or even detailed stripped the pistol yet. Total round count through the pistol currently stands at 537. If anyone else has any theories as to what the problem might be, I'd certainly appreciate their input.
