Hi We are flying into Philly, renting a car and visiting the wife's family in Doylestown for a few days, and then off to NYC and Long Island to see my family. This will be the first time I am flying with a firearm (US AIRWAYS) . I am bringing either my Glock 27 with night sights or Smith 642 with CT grips. I renewed my LEOSA in April for both pistol and revolver. We usually drive but the wife wants to fly this time. Which of these would you bring? Thanks.
