I fail to see how the five basic safety tips of firearms do not apply airguns as some have mentioned above. Clearly the OP violated Rule #2 and received quite a wake-up call. Whether or not you can clear a weapon (powder or air) in the same manner you still need to treat it as loaded all the time. The worst accidents happen when we "think" the gun has been made safe. Regardless I'm sure we've all experienced an AD to some extent or another - whether the firearms fault or our own.
1. ALWAYS KEEP YOUR FIREARM POINTED IN A SAFE DIRECTION.
2. TREAT ALL FIREARMS AS IF THEY WERE LOADED.
3. KEEP YOUR TRIGGER FINGER OUTSIDE THE GUARD AND OFF OF THE TRIGGER UNTIL YOU ARE READY TO FIRE.
4. BE CERTAIN OF YOUR TARGET, YOUR LINE OF FIRE, AND WHAT LIES BEYOND YOUR TARGET.
5. ALWAYS WEAR APPROPRIATE EYE AND EAR PROTECTION WHEN SHOOTING AND MAINTAINING YOUR FIREARM.
I agree with you and your list of safety rules but you missed some rules that are on my list.
I don’t know about you, but when I pick up a firearm, the first thing I do is always look in the chamber to verify whether the gun is unloaded or not. And before I hand someone a firearm, I always show them the chamber so that they can see that it is not loaded before I hand it over.
You can’t do either of these things with the vast majority of PCPs because you can’t see into the chamber to physically see that it’s not loaded and this is what I mean when I said that not all safety rules cross over from firearms to PCPs.
If I hand someone a loaded gun for some reason, I always tell them that it is loaded and I do not relinquish control of it until I’ve made eye contact with them and they make some kind of acknowledgment that they understood it was loaded. If someone hands me a firearm and doesn’t show me that it’s unloaded, I don’t take it without asking them if it’s loaded and to open it and show me it’s not loaded if they say no. I will not be friends with anyone for very long and I will not hang out with anyone if they demonstrate unsafe gun handling around me or are in a habit of handing over loaded weapons without at least informing me that it’s loaded.
Because you can’t see inside the chamber of most PCPs I will demonstrate to the person I’m going to hand it to that the gun is not cocked before I hand them my PCP. If I don't know if the person is familiar with PCPs or not I will explain to them that I can not show them that the gun is unloaded and why and I will explain that a safe PCP is a de-cocked PCP. I will also explain that if they cock it, they just loaded it regardless if there is a pellet in it or not. I will also show them where the safety is located and that the trigger is safe or disengaged before handing it over. I will even demonstrate how to de-cock the gun before handing it to them.
As I said, a cocked PCP in my mind is a loaded PCP because they can shoot anything that is in the barrel (like a small piece of rubber from a torn up transfer port seal in a used 1720T as I exampled in my story) not just pellets. Even the air blast from an accidentally discharged PCP can cause harm if it went across exposed skin or was directed toward the eyes at close range. The only safe PCP in my mind is a de-cocked PCP.
I’ll also add for those that say they do not use safeties. While I agree that one should never rely on a safety, I will not be friends with and I will not hunt with anyone who hunts with their safety off in the field. I had a high school buddy that I pheasant hunted with for many years. One day in the field I noticed the safety was off on his Ruger Red Label and I pointed it out to him. He told me he always hunted with the safety off because he was quicker that way. I don't know when he started that practice but I gave him exactly one chance to change his mind and to hunt with his safety on when he hunted with me. We never hunted together again and we are no longer friends.
