Didn't realize they had improved the action on this model. That's interesting. I do like the styling of the gun, and the one shown is a beauty. Colt, just my opinion, has made a couple of missteps along the way, but generally you can count on them. I like both my Colts and Smiths, both excellent pistols. Of course the good old SAA remains a sentimental favorite. Like a friend of mine said when someone asked him how many guns he really wanted, he said, speaking for many of us, "One of each."This a slightly later model 1878 New Frontier DA Colt that replaced the fragile first series of 1877. These were produced through 1907. I have had one for about 40 years. It's a 44-40 and is my favorite "using" pistol.
