No silly questions, just stupid answers and I hope this is not one of them. I have a smooth trigger on a Model 65-5 which is one of the reasons it is my favorite shooter. I can shoot that revolver double action better than any S&W I own. So, I say, the revolver is yours to customize according to your needs. Sounds like your 66-1 will be a working gun and not a safe queen. I say go for it. View attachment 761527
