First of all, the answer to your question depends on where (in what State) you live.
In Montana, (without a CWP) no problem, just throw your loaded pistol in the truck (or car) and drive anywhere you want (that includes to the range). When you get there, just strap it on (MT is on OC state) and walk into the range. In Florida (without a CWFL) you can have your loaded psitol in the vehicle, but it has to be in a holster or in the glove-compartment/console, but once you get to the range, it has to be be unloaded and in a locked container (technically) for the trip from the car to the firing line. There are many commie - Pinko - NoBama-loving states that don't allow you to carry a loaded firearm in a vehicle, and if you live in one of them, unloaded and in a locked containr is a "safe position". So here's what I suggest... You obviously know how to use a computer and the internet, and most states' "Codes" are available on line, so go do your research, and then come back and post the result for YOUR state.
