DDS, The p97 is a little bit shorter than the p90, and it is a lot more rounded. I wouldn't call the single action pull "crisp" thats a relative term, its certainly better than the pull on any earlier Rugers that I've shot. Still has some take up, but I don't find that to be any kind of liability when shooting.
And I do really like Ruger pistols, the p91, was the first handgun I ever owned, and I still have it, and love it. Big, ugly, and you can't hardly make it jam.
