I have one for my 9mm pistols. It works good. I hung a 3" red reflector on the side of a flower pot in the living room and shoot from my chair in the second bedroom we use as an office, about 40 feet. It does wonders for your trigger control. I use the cheapshot brand. When you hit the reflector is looks like a strobe light. You can set up a jungle walk in several rooms. Have the wife spot them around and you have to find them.
