OK, I'd spend some additional range time making sure the impact point wasn't me yanking the trigger.
Before trying heat on the sights, make sure they're steel sights. Some of the S&W value line guns had/have plastic sights. They can be quite resistant to moving and you definately don't want to heat them. Regardless of plastic or steel, you're going to need a brass drift and a hammer to move the sights. Probably also some applied muscle on the hammer.
To move the point of impact, you move the rear sight in the direction you want the group to move. The front sight moves in the opposite direction. If the front sight doesn't have a white dot, you could file it down to correct the low point of impact. If you want to replace the front sight, I'd suggest calling S&W customer service. Different height front sights are generally available.
BTW, if you try to remove the sights to replace them, S&W sights drive out from left to right looking at the slide from the rear. The slide dovetails are tapered. You install sights right to left.
