Picked up a G43 and I really like it. Last few years been carrying a S&W 9mm Shield , great gun. Now I just need to run some ammo through the 43 and see how it performs .

I've been using gold dot in my shield with no problems. Heading to range this weekend .   

I have the G42, wish at the time I would have taken the 43. It took me about 200 rounds to loosen up the spring and not have FTE and stove piping. I also had to put an extension on the mag so my pinkie could wrap around the grip and not dangle in the air.

I got an early G42 which apparently had issues (like yours). I brought it to a GSSF match and the Glock Armorer replaced a bunch of parts for free. The gun now runs flawlessly.

I bought mine in May of 2016. The numbers on certain parts indicated it came updated. Glock sent me newer magazines, and I polished the feed ramp. It was also suggested to leave the slide open for a few days.

Haven't had one problem since.

I carry a 43 in a blade tech holster every day.. good to go.. 

Do you carry the 43 straight or canted?  Have you tried the mag guts spring?  I have been using the pierce +1 with the bottom front rounded by my dremel.
