Hope this hasn't been addressed to death already, but my CCW class, scheduled for September 8, includes qualifying with TWO different weapons. Since I own only one, can I rent a gun like the next one I plan on buying and shoot with that? I won't be buying for a few weeks. My concern is that the CCW will list a serial number as part of the gun description, and of course, that won't be from MY gun. Anyone? Thanks in advance!
