I have a leather cover I use in hunting season. It was dosed with Sno-Seal years ago and it still mostly water proof.
My loaded hunting rifle comes to the house in the cover and stays in it till it goes out again. This is my "its loaded" flag.
Horror stories abound concerning ADs.
I was once in a room with someone with poor to non-existent firearms training, we soon discovered. He watched a friend load and holster his 22 revolver and say "its ready to go" and while the friend and I were otherwise occupied he picked it up and shot a hole in the ceiling of an adjoining room though the doorway (2 people in that room).
Neither I nor my friend could have known or even guessed this would occur.
The AD was TOTALLY the fault of the person who picked up something he was, unknown to us, unfamiliar with.
I once k new a 2nd LT in the infantry who had his M-16 fire a round while he was holding it. Fortunately it was not while he was behind anyone on patrol at the time. He could not maintain an interval either...
I was present on a range when a cheap factory made ML that was not properly set on 1/2 cock (cheap lock and triggers of course) went off while pointed straight up. How it missed the owners hat brim is still a mystery.
I once had a flint rifle fire when the cock hooked a vine and pulled back almost to full cock and then before I could stop moving the vine released it and the gun fired. Fly was not properly timed and kicked forward before the sear could catch the full cock. This was a 1960s not so cheap lock. For the past 40 years I now fix this "error" if it is present on any lock I get.
Back in the day people used to get shot by pulling guns muzzle first from a wagon etc.
Not so long ago a poster on a ML site was describing a friend being shot in the arm in this manner by a rifle musket that had been capped and then the cap removed to make the gun safe in a vehicle.
He stated that static electricity was the likely cause. The problem is the static will not ignite BP.
I explained that it was more likely cap residue on the nipple and in moving the gun the hammer rubbed or otherwise "excited" the residue. If it cannot be static is must be another cause.
The common thread in almost all firearms accidents is poor gun handling.
Working with firearms everyday requires a higher level of awareness so that constant contact does not erode ones safety processes.
Then there is the "other guy" problem. I used to work in a gun factory. One check was to fire a primed case to check firing pin strike to assure the breech block was properly positioned. The tester had a box of primed cases of various calibers that he primed in batches as needed.
Someone, the "other guy", in the shop found a "primed case" and put it in the box, but it also contained about 65 grains of BP and a card wad. As a result a brand new rifle was dropped on a concrete floor and the tester needed a "time out" (as did I being 10 ft away) for some time to collect his nerves.
Firearms require constant adherence to safety processes. Children in households with guns MUST BE TRAINED as soon as they are old enough to pick one up and function it. They must be DRILLED on the CLEAR THE GUN FIRST rule as well as how they function. They MUST be allowed to have supervised access to the guns and shooting to allow them to get over the curiosity/novelty phase. Hiding the guns, locking them up is a good security measure, unless its needed for defense then its just silly, but TRAINING and constant re-enforcement will last forever and always works.
I was recently in ML gun makers shop. We were examining ML firearms, sparking the locks, etc. HOWEVER, the loading rod was bounced on the breech of each. He KNEW they were safe. But he followed PROPER SAFETY PROTOCOL everytime. There simply is no other option. The firearm must be "cleared" before further examination.
I realize I am "preaching to the choir". But it needs to be restated now and then.
