You are already on the right track. Revolvers are not as popular as the once were with many people. For an everyday shooter you can not go wrong with the 686 you tried. My Favorites are the L frame Smith and Wesson which you shot and the K frame Smith and Wesson which is just a bit smaller. There will be very minor differences between shooting the Smith and Wesson and the Ruger. They are both well made revolvers and have a loyal following. I personally prefer the Smith and Wesson.
My rifle and pistol are tools, I am the weapon.
