Yeah, the 2.8/3.1/3100/3.4DOHC/3400 V6 engines from GM all experience piston slap. There is a TSB on it for customers that are anal about it, and a dealer will replace the pistons, and I think the wrist pins. But, not for free. GM knows about it, and honestly, I don't think I've ever heard of one of these motors breaking because of piston slap. It's not THAT bad. It does sound nasty though on cold startup, especially if the air temp is wicked cold.

These engines also experience lifter tick, but that's sort of normal with any engine. So long as it goes away, even just mostly once the motor is warm, I wouldn't worry about it.
