Saw a new Model 632 .327 Magnum yesterday with front and rear night sights. Really like the sights, wish they were available on a sa/da model.
Web page lists the new Model 640 in .357 Mag with tghe new night sights.
Yep. These look really nice. The biggest "problem" with the J frames are the crummy fixed sights. The three dot sights are going to be a BIG improvement.
