For the States your CCW isn't good you can lock the handgun in something like this. I bought this unit to take my compact Ruger LC9s with us to S.C. when we flew out to buy our new to us 2016 WS31. Meets TSA airline firearm guidelines & approved as a firearms safety device by the California Department of Justice. I always had the gun bedside at night as we worked our way back across the U.S.
