As a new handgun shooter myself I have no advice to offer, but 12" groups at 25 yards is nothing to be too ashamed of first time out. It took me an hour to get down to 3" groups... at 5 yards :/
It's definetly not as obvious or as easy at it seems at first is it. In fact I'd say it's harder to be a good pistol shooter than a good rifle shooter.
My own first time out wasn't much, if any, different than yours.
