As much as I love Smith and Wesson, no gun is perfect.
Smith and Wesson, and Ruger revolvers are about as close to perfect as you can get. Let's not also forget Colt and Dan Wesson too.
Any of these four are great investments, with my personal favorite being S&W. Each maker has their following, and for good reasons.
Ruger: many consider to be the toughest
Dan Wesson: excellent quality, plus versatility with their interchangeable barrels.
Colt and S&W: Timeless classics, beautiful styling, durability, accuracy, all around great guns. Absolute love for them.
