Does anyone have any personal experience with 4 and 6" .357 from Tarus, Rossi, etc. as well as an S&W that can give an honest comparisson? What I'm really curious to know is if the extra money is just because you're buying the name S&W or is the quality really that much better? Also, what are the advantages of having a 4" compared to a 6" and vice versa? I've owned a 2" Tarus .38 for years and love it but I want to get a .357 for more stopping power and home defense. How much difference does the barrel length make when it comes to kickback, accuracy, etc? I'm asking because as a law enforcement officer, I've only shot .40 semi autos for my entire career and know next to nothing about revolvers. Thank you in advance.
