This is what I did- military tubular webbing cut to fit around my seat and then some, sewed some buckles to it. Then I sewed a 20$ holster to the webbing. Keeps my gun right between my legs in a safe place. If I get in an accident, it's not gonna fly around my car, and I can easily retrieve it if necessary.
