I recently got a 629 Classic with the power port, I have only had it out to shoot one time, but I like it, it's quite accurate with either full house 44 mag loads or milder 44 special power loads. I have shot double action revolvers in competition so I'm used to double action shooting for accuracy, the only thing I had to do with this one was to replace the trigger rebound spring with a lighter one from Wolff springs, I didn't mess with the hammer spring at all, after replacing the trigger rebound spring I had a trigger I could work with.
