I would appreciate any advice and input. My dad had a stroke two years ago at the age of 80. He has been a gun-owner and hunter all his life. He now suffers from memory loss and dementia or Alzheimers depending on which doctor you talk to. He still lives at home with my mother and often suffers from depression and paranoia. Lately, at night he often thinks someone is in the house. I told my mom to hide his gun (.22 revolver) but she said he knows where it is and checks it every night and if she were to hide it he would get very agitated and even more paranoid. So I told her to hide the bullets but he keeps the gun loaded and also checks to make sure the gun is loaded. My brother removed the bullets last week and it made my dad more paranoid - he was sure someone had come into the house. So they allowed him to reload the gun just to calm him down. He has yet to make any attempt at grabbing the gun but I'm still worried about it. I want to know if, and where, I can buy some .22 blanks or other false bullets to load into the gun so he will think it is loaded. I am very worried that he may mistake my mother for a burglar or accidentally shoot himself. My brother and I are in agreement that he doesn't need to have a loaded gun within reach. Would the gun have to be modified in order to load blanks? Or should I remove the firing pin? How can I disable this gun without his knowledge? Do I need a permit to purchase blanks? Any advice? Thanks in advance.
