The grooves on a slug are to seal for gas pressure while allowing the slug to swage down in the various chokes safely. The sabot slug is a smaller "bullet" like slug in a 2 piece "sabot" of plastic. In a rifled barrel the rifling imparts spin on the sabot that leaves the "bullet" upon exit and the bullet flies in a spiral for a longer range accuracy.
To me the difference is a more expensive gun firing slugs at 10+ dollars for 5 compared to a sub $200 gun firing slugs that cost $10 bucks for 15...
Your gun is ready for the latter...
