I have a 1st gen (1935) in 45 LC, with all new Colt cyl, barrel, hammer, trigger, and guts. Don't matter to me, it's just a tuned shooter gun. If it was antique age, maybe I would think different. I don't know what the gun looked like before the surgery, so it is what it is. A nice shooter. I think do what makes you smile.
Yes, I suppose I shouldn't be surprised. If someone says it on the internet, it must be true.
