39, 39-2 and 59 had a windage adjustable rear sight that I like a lot. The 2nd Gen fixed rear sight is perfectly fine and the 3rd Gen Novak fixed rear and factory night sight fixed rear are fantastic.

However, the 2-3rd Gen adjustable rear sight is simply hideous in appearance. It has protective wings that would look fine on an armored personnel carrier but look obnoxious on an otherwise handsome pistol. Besides the awful appearance... I still cannot understand -why- anyone believed this was necessary-- cops all over the nation carried S&W's adjustable sight revolvers for decades and decades of hard service in harsh environments and those rear sights basically NEVER fail, so I am at a loss for what needed "protection" in the 2-3rd Gen adjustable rear sight.

Just plain awful looking. It actually looks like they couldn't possibly have made it look worse if they wanted to.
