I also like the Python's stacking trigger for range shooting or self-defense, but the 27 would probably be more suitable for target or competititive tactical matches.

Let's see, what to do?.... Oh, I know; get several of each.

I have to admit that I sold my 27 because my heart is more into the K-frame 19's and 66's.
But I've got 3 Pythons (Blue/4", SS/6", Halliburton Hunter Set) and 3 K-frames (Blue/6", SS/2-1/2", SS/4"), and none of them are going anywhere anytime soon.
It's nice not to have to choose one over the other.
