Bosshoss is correct; you are not limited to just one. I have both: two 5" 625s (one for bullseye and one for steel plates) and a PC 627 5". I also have a 5" 629. The feel and balance of a 5" N-frame is very nice. I never cared for the 4" barrel length. The 5" seems to have a better balance and a little longer sight radius. Moonclips make reloads very fast, but the 45s seem to load faster than the 38s. Also, moonclips make brass recovery easy.
I have a couple PC guns from S&W. They are nice, but I do my own trigger work, so that is not why I would get one. I wanted the PC 627 because it had the 5" barrel. The pro model is the 4" barrel. The 625 PC is 4", that's why I did not get one of them.
One nice feature on the 627 is the front sight is easily changeable and you can add fiber optic, gold bead, or whatever type of sight you like. Adding the fiber optic front sight to my 625 took more work and can be a little tricky. I use Moonclips from Ranch Products for both models. They are very good, dependable clips and are the best price I've seen for moonclips.
