I have two of the newer S&W revolvers, the Model 21 & 22 Classics. I bought them simply because I liked them. The classic lines of these revolvers have a certain nostalgic charm. Both are tack drivers and I sure wished my Beretta 92 could hit with the same accuracy as my Smiths.
Do I like the lock? Nope, but I really love the look and feel of revolvers enough that they were worth every penny and have no regrets whatsoever about buying them and would do so again.
