I hope I'm misinterpreting this but just in case I am misreading something I'll check.
Are you in fact saying it is perfectly safe to holster and carry a loaded and cocked single or double action revolver ?
As long as we get the right to disagree, if that is what you have been saying I WILL disagree ,,,strongly.
Personally I can't think of a more unsafe gun handling practice for you and every one else around you. On the same level as Russian roulette ,because it's just a matter of time until something goes wrong.
Seriously, you need to call Ruger and run that transfer bar theory by them.
The transfer bar was developed to keep the firing pin off the primer so 6 rounds could chambered ,,,,,, with the hammer down. Period.
It has not and never will be viewed a cocked gun safety but it might save you if a cocked gun is dropped.
