Building your own firearm is the best answer when privacy is a priority. Handguns built with the Patmos Arms G21 slide and other parts from JSD Supply don’t require a background check. There also aren’t any government fees and it’s up to the designer whether to engrave the finished handgun with a serial number. This gives you a professionally finished piece that will be absolutely confidential.
