$5.00 case all the way.
1. It's a handgun case
2. It is lockable
3. I'm reasonable sure it can't be easily broken into as it is in my sight from my house to the range. The law says I have to take the most direct route so If I want a coffee I go through one of the billion drive-throughs available, ergo the gun is locked in the vehicle with me as my vehicle, as most do now-a-days, has automatic locks. If someone puts a gun to my head at the drive-through and steals my pistols(s) then I am still covered legally as I am transporting them to the letter of the law.
4. I don't store my handguns in my transport cases
5. Willing to buy used $5.00 pistol cases for $2.50
