On the S&W website, the 66 (2.5") is listed at 32oz and the 686P (2.5") is listed at 34.5oz. In an article in Gun Tests, they list the 66 at 36oz. (unloaded). What's the real deal? I would think that the 686p with a 7 round cylinder and being an "L" frame would be a lot heavier. Is there a big difference in how they "feel" for carry purposes?
