When I was in my middle teens we had a family friend we'll call "RR". RR served in WWII as a bomber pilot, he was shot down over France and escaped back to England with the help of the French Resistance. RR was a fluent French speaker and was recruited into the OSS and returned to France several more times during the war. After WWII RR was recalled to active duty to fly bombers over Korea, needless to say RR had seen some @#$% and had been there and gone that. We would often go to the range with RR and to this day I still remember his range safety talks and the steps we took to insure everyone was handling their firearms safely. One year RR came deer hunting with us, RR and I where walking back to camp side by side from the mornings hunt and my father
@Shootist43 noticed that the hammer of RR's 35 Remington was at full cock and the muzzle was pointed at my head. When dad told him to put the rifle on safe and point the muzzle in a safe direction RR's response was and I quote "Art it's ok we're hunting", RR left camp the next morning and we never went shooting or hunting with him again.
When I was in my early 20s I shot competitive bulls-eye with a guy named Bobby Plante, Bobby was so good with a hand gun he became a member of the US Olympic shooting team. Bobby had a bad habit, if he fire a bad string which was almost never he would raise his pistol to his head and say bang. Every time he did that we would remove him from the range and suspend his shooting privileges for a time. After making the US Olympic shooting team Bobby moved to the OTC in Colorado, one day the Mexican National Shoot Team was there to train and they learned that Bobby shot and worked on 45's, one of the Mexican team members arranged to meet Bobby and one of Bobby's team mates in his room to look at his 45. In Mexico the 45 is a military firearm and can only be owned by special permit and is commonly used by its owners for home defense, it is normally stored with the chamber empty and a loaded magazine in the gun. Bobby took the 45 from the Mexican shooter and racked the slide to make sure the gun was empty. At this point the Mexican shooter became frantic and started speaking in Spanish a language Bobby did not understand. In an effort to prove to the gun owner that the firearm was safe Bobby calmly raised the 45 to his head and squeezed. Bobby's US teammate testified that after the gun went off Bobby looked at the 45 with stunned shock before collapsing to the floor.
The first incident resulted in the loss of a friendship the second in a tragic loss of life and both could have been prevented by following the three basic rules for handling firearms:
1.) Treat every firearm as if it where loaded
2.) Always keep the muzzle pointed in a safe direction
3.) Never put your finger on the trigger until you are ready to fire
I don't care how you carry your firearm but if it violates one of those rules you need to find a new way to carry your gun.
