I like (mine)
I bought a 720 with no rear sight for $200 in a private sale (yes, in Florida, you can still do that!). I promised it to my son-in-law for Christmas, and one of the people who frequent this board located a rear sight for me... and then I took it for a test run before I gave it to my son-in-law. Wow. It shoots better than I aim, and the overall feel/recoil is a real pleasure, especially compaired to any of my .357's (surprise!). Mine (well, now, my son-in-law's) has adjustable sights, and they are extremely easy to pick up and point. If I get a chance to buy another, I certainly will, and if you get a chance to buy one, you better get it before I do!
