I am thinking of picking up a new revolver. I can't decide if I want 45acp or 357. I am looking at the 625 or the 627. I would like a 4" barrel, but not sure if the performance center is worth the extra for me. If I have the free time this coming year I would like to do the bowling pin shoots with a revolver. Also be used for target shooting. I have the capability to reload either round and like the idea of the moon clips. Any benifits of one over the other?
