Nice to see a MagnaPort thread here. I had this done several years ago after reading a review that Layne Simpson did for Shooting times. In that article, a 629 and 617 was reviewed, both custom by MagnaPort. I was very pleased with the results. I had the glass beaded finish, polished hammer/trigger, pinstriping and a triggerjob performed. No trapezoidal ports needed as this was already a powerported model.
