If you were to drive to Florida and then fly home...would you:
Buy an inexpensive but dependable pistol in case the airline loses it?
Or
Carry a normal EDC in your rotation and hope for the best?
Carry my normal one. EDC is meant to be used, not to be a BBQ gun. I've flown with my firearm many, many times and never had an issue. If for some reason the airline loses it, I would just bite the bullet and buy another...
