GM Puck system gooseneck hitch

[Baconator]

I bought a new GMC 3500 that has the gooseneck puck system installed and came with the GMC branded-Curt ball. It fits really loose, and when I hooked a gooseneck to it I swear I can feel and hear it clunking back there. I didnt measure it, but I bet the ball moves ~1/4" at the top of the ball.
Any feedback on other brands of drop in balls that fit the puck system? I like the look of the B&W, but dont want to drop $300 on something that might not be any better.

Take it back to the dealer?

Take it back to the dealer?

Normal for the Curt hitch apparently. Just looking to see if anyone has a B&W or other brand that fits better.

I have the same setup and it doesn't seem that sloppy.

Shims, or braze a few bronze beads on the ball that are then filed to fit nice and snug.

Bring it back. If it keeps happening bring it back again. I don't fuck with anything that has a warranty

All 3 of mine have cluncked like they are loose, all new trucks. Seems to be an issue people complain about on the FB groups, they say the B&W fits better and isn't as bad. Other than the noise I've never had an issue with it, I don't even pay attention to it anymore.

I stopped at the dealer yesterday and had the service advisor look at it, he said normal, lots of people are complaining and GM says its fine.
Drives me nuts, pulling a 20k trailer around I dont want to hear the fucking hitch bashing around.
