To clarify, YES YOU CAN DROS A PISTOL FRAME ONLY, AND NO SHD IS REQUIRED. When the FFL enters the DROS info there is a drop down menu "frame only- yes or no". When yes is selected, the field for caliber is deactivated. For your reference: http://ift.tt/1U07CQc?
I always find it interesting when gun stores don't know wtf they're talking about. Scary, yet interesting.
Is SHD required for frame only sale? NO
