I have a 34-1 4" and the new SP101.

For me, the SP feels much better in the hand, balances better and has better sights. The accuracy is a push. The Ruger's fit/finish was good to great. It's not a fine 30 year old S&W, but it's not made to be either.

Unlike Cajun Bass, I found the trigger to be smooth. Very heavy, but smooth. I swapped the heavy factory hammer spring for a 10# Wolff spring and it made a world of difference. ~400 rounds later, no FTF with the lighter spring.

If I had to sell one, it would be the M34.
