Prepare the grill for high direct heat, preheating until it is ready. Oil the grates.
Trim off excess fat and salt and pepper both sides of the pork chops.
Add to grill over direct high heat with lid closed. Cook for 2 minutes.
Turn pork chops over and continue grilling, lid closed, for another 1 minute.
Reduce grill to medium low with a gas grill or move chops to a cooler portion of the charcoal grill.
Brush a liberal amount of barbecue sauce on the chop and flip. Brush barbecue sauce on the upward side as well, so that all sides have been sauced.
Cook for another 1 minute or until the internal temperature of the chop is 145° F.
Remove from grill and let rest for about 5 minutes.
