What a great site! I've been lurking for some time and have learned a lot about S&W's. I have a decent gun collection, but it is seriously lacking when it comes to the revolver dept. After all the lurking I have done on this site, I have concluded that a 686 is in the near future for me. I am just having a problem deciding between a 3" or a 4". I am mostly interested in how each of them balance and how comfortable to shoot. Any input would be appreciated!
