Bad idea. While you can get a decent set of cuffs as a civilian, it takes proper instruction and training to use them the right way. You never seen a lone police officer holding his gun on a suspect and trying to cuff him with just one hand. There's a reason for that. You never want to close the distance on a potentially dangerous, experienced, criminal. While you're using one hand to try to cuff him, your concentration is on that task. It's not on your gun. Experienced criminals know that. They might let you get one wrist cuffed. But as soon as they hear that ratcheting sound, they could easily turn on you. Average homeowner struggling with a career criminal who has trained himself in firearms disarms and other tactics? Not good. Or, he just goes for his own gun instead.
If you're able to get the drop on an armed home invader, always keep your distance. Keep your weapon pointed on him. If he raises his hands, keep a constant eye on him, call the cops, let them know you're armed and who you are (homeowner), keep your distance, wait for the police to arrive. Let them cuff him.
