Yes, kind of. The lawman and mark whatever had a ejector houseing and a SOLID rib, not vented and tapered. The action was redesigned and they have a shorter grip frame. The action was less complicated but not as nice as the python. They were more similar to a model 19. I had one or two many years ago but just turned them over.
Here are my two pythons. By the way I found the same holsters will fit the troopers, pythons, my m&p and the 66. I also have a 5" 27-2 and a m&p. Forgive me if I am boreing with repeat pictures. I belong to several sites and cant remember which I posted where on similar subjects. Let me add, I agree the large target stocks on the python or troopers are less comfortable than smiths are for me too. However the goodyears on the python shown feel just great. They are flatter. I am ordering some faux ivory from Boon tradeing company that look good. I will try them out and report back. Check out this picture of them. The mustangs on my 2 1/2" feel great too.
