Oh, and don't carry a valuable antique or a family heirloom. If, God forbid, you ever do have to draw your gun, expect that the cops investigating the "incident" will seize and impound your gun, and if you ever do manage to get it back, it will look like it was stored in the septic tank while in police possession.
That's why I've not really considered carrying the P-38. It's a real German WWII gun that was given to my father (who fought in WWII Germany) but it was given to him by a former German officer years after the war when my Dad was stationed in Germany again in peace time.
