I, for one, have never been fond of ported barrels. Recoil is the function of bullet weight, gun weight, and muzzle velocity, and I havent found porting to greatly affect it. Maybe so some longer barrels will have the muzzle flip reduced, but I've not found it worthwhile.
As to tweaking, action jobs, etc, I usually leave my guns alone, especially Smith & Wesson revolvers, as I've found them to have the best DA actions of any.
My suggestion is to shoot the gun as is first, with the ammunition you intend to use steadily. Run a couple of thousand rounds downrange before you decide to do anything.
