Several months ago, I asked a dealer to order for me a Ruger KGP 141 (4" barrel, full underlug, adjustable rear sight, stainless steel). After 3 weeks, the dealer still had not been able to locate a Ruger with the specifications noted above (3" and 6" barrel models were available, but no 4"). So I let the dealer sell me a new Taurus Tracker M627 with the above noted specifications + ported barrel and rubber recoil absorbing combat grip. A couple of weeks later, a poster on the TFL handgun forum offered a Ruger LNIB with the desired specications, so I bought it.
A couple of weeks after getting the Ruger, I took the Taurus back to the dealer and traded it for an in-house credit toward a future unspecified (and at the time unknown) purchase. I didn't care what I might get for it, I just wanted to get rid of the Taurus ('turned out, I got a LNIB 870 Police Magnum - what a bargain!) Why did I want to get rid of the Taurus? Because the Ruger manual recommended unlimited dry firing, whereas the Taurus manual said something like "Dry firing is bad for this revolver, even with the stricker plate (engaged or disingaged or something like that)". The Ruger is a more rugged gun, and I like the way it looks and feels.
I will say this for the Taurus Tracker: zero perceptible recoil, like firing a cap pistol, with full magnum loads (145gr and 125gr). The Ruger recoil hurt my wrist (age 67 with a tinge of arthritus), so I have sent it to Jack Weigand (Weigand Combat Handguns) for barrel porting, precision action job, and Ashley Outdoors Express Sights.
So, If you want a revolver which inflicts zero recoil, and if you don't mind not being able to dry fire it, the Taurus is the cheaper gun and might satisfy you. Being a perfectionist, I do not mind putting the extra money into customizing the Ruger.
