I going to say that Harton the gunsmith would be the best idea. I fired the Blackhawk and found the trigger not too bad. I have a Savage rifle with Accutrigger and a 22lr Anschutz with 2&1/2# trigger. The Ruger Blackhawk wasn't heavy on the trigger and has just enough creep to give me a few seconds to get the sights aligned. It's really shootable.
After I get the equipment together to reload for it, I may have the trigger done but, I don't know if I'll feel it needs it. I did notice that out-of-the-box the pistol functions are dirty, lots of grit from the machining process. That does have something to do with it. If one doesn't have a high degree of mechanical ability, leave that to a gunsmith. Personally, I can tune Quadrajet carburetors but, the single action is complicated to the average shooter. I found it on par with the mechanism of the Pre-G2 Contender. Other than that, gritty and dirty, lacking lubrication. That makes it shoot and function rough anyway. A good trigger job wouldn't hurt a thing.
