Other than widening the range of selections among our group, this post may be of no value given the non-stock status of the revolver I have selected. So proceed with that caveat.
My easiest to shoot revolver is my customized S&W L frame with a 6" bbl. This revolver has a match (not duty) action job. From my PPC competition days I shoot DA only, so a smooth, light DA pull is very important to me. If this particular revolver is not the smoothest and lightest of all my revolvers, it is a least enough of a contender to leave the issue unresolved.
During this same era (80s) Wichita Arms offered a stainless steel barrel shroud for S&W L frames, and other similarly configured revolvers. This shroud is heavy, replicating the weight of a bull barrel, plus it is extra length (and thus weight) because it has an integral recoil compensator. One of the road tests of this rig stated that shooting .38 wadcutters felt like shooting .22 rimfire rounds. I had to have it.
That heavy muzzle dampens any sight disruption from the long DA trigger pull. .38 wadcutter recoil really does feel like .22 rimfire.
The downside is that, all up, this is a lot of weight, somewhere in the 60 oz range. It is unwieldy to carry, so I use a PPC holster. It is the antithesis of speed and maneuverability. One has to be prepared for the weight and its muzzle heavy bias when picking up this revolver.
But when I roll back that smooth, light DA trigger, and experience virtually no recoil, thus facilitating accurate follow up shots as quickly as I want them, it is revolver perfection.
And that is my easiest shooting revolver.
