To start, I’m not very knowledgeable in fire arm specifications, but I am in law and the criminal justice system. As far as it goes for home defense with this firearm, i can only suggest that you do not use it. If you do use it for self defense in your home, and you use it and injure/kill someone, (first of all, as soon as you fire your gun in self defense, you are going to court), any lawyer worth their salt will point at your gun, and if it is full of modifications, will say something along the lines of “they were waiting for an excuse to kill someone, or hurt someone.” Or “they did everything they could to make the firearm more deadly”. “They didn’t need to kill my client, they did it because they wanted to, not because they needed to.”

Especially depending on if you are in a state or country that is not very gun friendly, the appearance of your firearm could be the difference between jail time or freedom, huge fine/confiscation of your firearm or not.
