You are right, I am not an engineer. The ROA is a black powder revolver. No black powder revolver ever had a transfer bar, and I, for one, would not want one. Looks to me like after you fired it a few times the powder residue could get behind the transfer bar and it wouldn't fire at all. Ruger had the Old Army with notches between the chambers to safely rest the hammer in. That's all the safety it needs.Then your engineering IQ is minus 47.
A transfer bar works with a frame-mounted firing pin. Percussion caps need a flat surface (hammer nose) to fire them, not a pin suitable for a modern primer. And as stated before, the ROA cylinder has a 'safety' notch between each nipple where the hammer nose may safely rest when carrying the pistol with all six nipples capped.Then your engineering IQ is minus 47.
True, Ruger starting installing TBs to avoid lawsuits and to protect certain people from hurting themselves. Apparently you are one of the people it was designed to protect.Are you serious.? TBs are a great safety invention. And a great way for a company to avoid lawsuits.
