Well, here's my take....and this is from personal observations over four years of working with a revolver on my hip.
1: The Smith 686 4" is probably the finest combat revolver ever designed. The only drawback to the serious user would be the fragile rear sight. Of all the thirty-plus revolvers in our weapons locker, the only visible damage is to the rear sight leaf and the rubber combat grips. All of the weapons are tested annually for function and they always pass, regardless of cleanliness.
2: The position of the grip on a revolver positions it at the highest point on the weapon as it sits in a holster. This means the path to the grip is not obscured beavertails/tangs. Whether your hand travels up to the grip or down to the grip, it is far faster to access than on 99% of the autos out there.
3: My personal weapon has seen very little cleaning in four years of use. At first, I was anal about cleaning it, but I got curious about how dirty it could get and still function. Right now it sits in my duty-belt holster covered in soot from several hundred rounds fired on Sunday. Dry-firing shows that everything is working as it should.
4: Accuracy is what you make of it. To say that you can't shoot a revolver for squat is to state simply that you haven't spent enough time behind the trigger of one. I can keep all of my rounds inside of a cardboard target (16"x16") when shooting rapid free-hand at 25yd. That's roughly the size of the average ribcage and isn't too bad. From a rest, my groups are tighter because a lot of me is taken out of the equation.
5: Trying to transition to a Colt 1991 for reasons of capacity and such has shown me recently that there really is a lot to the Revolver. Trying to snake my thumb around the beavertail to engage the thumbreak is slower...to say the least.
6: The various grips out there for a revolver can greatly change the feeling it gives to the shooter and, therefore, the way it shoots. Hogue wraparounds might be too big for the smaller shooters, but the same gun with cheap wood slabs might turn into a tackdriver. I've seen it happen countless times.
Make the most of it, folks. If you "can't shoot a wheelie for beans", get out there and spend more quality time with one. Look at it like a challenge. I dare ya!
