Covers all S&W manufactured firearms, including rifles, shotguns, and submachine guns, up through 2001. This is a much expanded version of the first edition. IF you have the 1st edition, you still need to buy the 2nd edition... .there is just that much more info on model variants, and more photos. If you are a SW collector, you will sleep with this by your pillow. One of the best reference books devoted to S&W I have seen, more comprehensive info on the models than Roy Jinks' History of S&W, each variant of each model is explained in detail, with stock number, changes made, ways of identifying each variant, some serial number info, lots of photos, etc. The info on non-handgun products is about 10 percent of the book, and it covers even the S&W handcuffs. The info on the handguns is what this book is about, and it does an outstanding job. I'm an S&W wheelgun lover, and this is one of my most valued books. And the short history of the company is fascinating as well. IF you like Smith & Wessons, you absolutely must put this book on your shelf.
