mlebler, beautiful Security Six! Looks like the one on EE I missed out of, several days ago.
After 20 years of shooting S&W K and L frames, 22 months with a GP100 and about 3 months with my Security Six in stainless, I must say my new favorite is the SS. Modern design philosophy by Ruger addressed the weaknesses of the old traditional S&W revolvers.
With a Hogue grip, it fits my boney medium sized hands better than the other revolvers mentioned above. I prefer its size, weight, balance and pointability.
The Smiths have better triggers but I am happy enough with the SS's other qualities to overlook this one minor flaw. I can still shoot my Smith's better, due no doubt to their triggers, but I will get used to the SS for sure.
While I still prefer the fit, finish and aesthetics of S&W, I just love the tight and solid feel of my Rugers.
BTW, the SS has two locking points, similar to the S&W K and L frames. The GP100 has two as well; it has the crane lock but no front bolt/lug.
