Home defense rethink. What do you guys think?

After a day at the range it occurs to me that if I discharge a firearm in an enclosed area such as my hallway, I will be struck instantly and probably permanently deaf. I have a couple of paintball markers that I am thinking may be as much or perhaps more suitable because they stinking HURT when you get hit in the neck, face, or genitals, especially at close range. These may make it easy to distract the intruder and cause them to flee due to the high cyclic rate. AND I wont have to mend my walls or worry about the neighbors. What do you guys think?
