I am the second owner. I seem to recall that the original owner told me that he ordered it that way. Have no idea if this is true or if S&W did special orders like this. It is so pretty that I left it that way.
The trigger is so smooth that I was sure it had been worked on by a professional 'Smith. The previous owner said it was stock. I just know that it the sweetest trigger on any gun that I own.
I also purchased a 7 1/2" Ruger Redhawk in .41 Magnum from the same guy in the same sale (I am a great fan of the .41 Magnum). It was manufactured in 1989 and came with a barrel with the scallops for rings and a scope. Never got the rings, but love the Ruger too. Trigger on that one is not nearly as nice. In fact, it is rather heavy.
Still another .41 that I own is an 'Old Model' Ruger Blackhawk, with 6 1/2" barrel that has been decked out for me by Gary Reeder. That handgun is beautiful and has taken Javelina and Pronghorn Antelope.
