I'd look at it from another perspective. You mention that you need a pin gun, I'm assuming for bowling pin shooting? I'd also wonder how much shooting you plan on doing. If it's once in a while, I'd go with the Colt, if it's every weekend / even a couple of times a month I'd go with the Taurus and for one reason: They're still in production and you're covered by a lifetime warranty. For Colt, well, they made nice revolvers once upon a time. Any heavy amount of shooting will eventually wear out the revolver and it's a lot harder getting the replacement parts and finding someone who still knows how to work on a Colt.
