In our area, it is common policy at most departments to lock your weapons (gun, knife, etc.) in a gun locker before entering the jail. Problem is, you can get a “hot call” and jump in your car, leaving your gun at the station. Yikes!
I’ve started locking my gun in the trunk of my car instead. I then rest my baton between the “spokes” of the steering wheel. Then if I jump into the car, my baton resting on the steering wheel reminds me that my gun is in trunk. Works well for old guys like me...
