The N frame is at the end of my limit on size, and the Hogue grips that came with my 629-5 did not let me shoot double action. I can not consider a Tyler T Grip because of the aggressive recoil of the 629-5 so I settled on a set of Pachmayer Decelerators. They are thin and give me the ability to shoot double action, and have a little extra padding to absorb recoil.
