Other than that you've got a choice of 25 and 50 yard target positions on the pistol course.
Practice at that distance and 25' will be easy.
My max "able to shoot" distance is 35', my minimum is 12'. I won't let the BG get too close before taking him out. I won't "clear the house" - that's for professionals. I'll bunker down and wait for him to come to me. Surprise, BG! No one but my wife and I should be in my house so anyone else is an intruder. Several years ago, our Sheriff made a statement. He said that if someone enters your house, you may assume they're there to harm you, not to just burgle - act accordingly. SC has the Castle Doctrine law, too.
