Personally I wouldn't get all wrapped around the axle over the wording of Rule 1 from any one particular source.
Even Cooper himself varied the presentation of the Four Rules from time to time. One later version went thusly (this one from Cooper's Commentaries, v. 11 #4, April 2003 -
http://harris.dvc.org.uk/jeff/jeff11_4.html ):
We hoped by this time that the standard rules of safe gunhandling would have become universal throughout the world. They have been arrived at by careful consideration over the years, and they do not need modification or addition. We trust that all the family have them by heart in all languages, but for those who came in late here they are again:
All guns are always loaded. Even if they are not, treat them as if they are.
Never let the muzzle cover anything you are not willing to destroy. (For those who insist that this particular gun is unloaded, see Rule 1.)
Keep your finger off the trigger till your sights are on the target. This is the Golden Rule. Its violation is directly responsible for about 60 percent of inadvertent discharges.
Identify your target, and what is behind it. Never shoot at anything that you have not positively identified.
Those will do. We need all four and we do not need five. It should not be necessary to belabor this issue, but life is not perfect.
--------------------------------------------------------------
Elsewhere, Rule 1 is expanded thusly:
"There are no exceptions. Do not pretend that this is true. Some people and organizations take this rule and weaken it; e.g. "Treat all guns as if they were loaded." Unfortunately, the "as if" compromises the directness of the statement by implying that they are unloaded, but we will treat them as though they are loaded. No good! Safety rules must be worded forcefully so that they are never treated lightly or reduced to partial compliance.
All guns are always loaded. Period!
This must be your mindset. If someone hands you a firearm and says, "Don't worry, it's not loaded," you do not dare believe him. You need not be impolite, but check it yourself. Remember, there are no accidents, only negligent acts. Check it. Do not let yourself fall prey to a situation where you might feel compelled to squeal, "I didn't know it was loaded!" (from

And you can see what our friend Xavier has to say about it at

http://xavierthoughts.blogspot.com/2009/02/rethinking-rule-one.html .
I think the point of it all is that ANY gunhandler/shooter MUST ALWAYS satisfy himself/herself directly as to the condition of ANY firearm the moment it comes into his/her hands. If said gunhandler is not familiar with the firearm and does not know how to clear it, a simple polite request that the action be opened and the status of the firearm displayed clearly is not out of line.
As far as one's own firearms are concerned, the first thing a gun owner needs to do is to get familiar with how said firearm operates and its manual of arms. To this day I still hear of people who, having cocked a hammer on a chambered round, don't know how to get the hammer down without firing the round. The latest one was a couple of weeks ago on a reproduction of the old Winchester 1897 pump shotgun. Uncocking an exposed hammer over a chambered round is indeed a touchy bit of business, but it's a skill that needs to be mastered- preferably with an empty gun. These days of course designers have given us decocking levers on some handgun designs and various manual safeties on different modern production lever action rifles. But we still need to observe Rule 2 even with these 'improvements' in place.
As far as eventually being comfortable living with a given firearm in a loaded condition- it might very well take some time for that to come about. My first carry gun waaaaay back in the mid-1970s was a S&W J frame revolver. Not a lot to worry about there as far as determining condition was concerned- it was easy to check. And it took a fairly stout pull on the trigger to make it go off, as long as the hammer wasn't cocked.
But around the turn of the decade, as the '70s rolled into the '80s, I bought my first Colt 1911. It was kinda disturbing, seeing that cocked hammer with a round in the chamber and just that little safety lever to lock everything. It took me a bit to get used to it all. And my 'crutch' while I was learning to get used to it (with the help of a friend who was a long time 1911 shooter) was to always keep the loaded .45 in a good leather holster that covered the trigger guard and pretty much blocked access to the safety as well.
Along came the '90s, and I needed to go somewhere for a while that was exposed to salt spray. Those Glocks with their Tennifer finish were supposed to be pretty durable, so I bought a Glock 19 so as not to have to expose my Colt to such harsh conditions when I might not be able to pull maintenance on it. And I had to transition again. Once again, my 'crutch' while I was getting used to the new design was a good holster that fully covered the trigger guard, used religiously while the pistol was loaded but not actually being fired. And making sure that I always religiously observed Rule 3 as well, especially when putting the pistol back in its holster.
Nothing says there can't be a safe transition period while learning to feel comfortable around your own loaded firearms. Nothing says that any reasonable, safe approaches to learning to be comfortable around your own loaded firearms are wrong. But I think it is better in the long term to learn to be comfortable by learning and practicing the standard accepted approach to firearms safety- and that's the Four Rules.
