Well for a FIRST Model 27, I would think a range gun is the way to go. I am very fond of the 6 1/2" barrel with a red insert Patridge front sight like the middle revolver in the following image
For carry, I really like the 3 1/2" eight shot Model 27s.
I prefer blue, but they were also offered in nickel
If carrying a N-frame is something you think will bee too heavy, there is the Scandium alloy framed 2 1/2" Model 327 which weighs in under 30 ounces
For pin shooting, I have recently added a 2nd cylinder to my 627 V-Comp so that I can shoot 9x23 Winchester or any of its related cartridges. The V-Com reduces muzzle climb to almost nothing when shooting 9MM ammunition. It comes back in target VERY fast
For fast followups even with the biggest, full power Magnum ammunition out there, this 627 Heavy Hunter is just amazing
The 27/327/627 family of firearms is extremely broad and diverse. It is hard to love just one
