I have both Security 6 and GP-100 revolvers. I really like both of them. The GP-100 has the advantage of being a newer and stronger design with some trendy features like the full lug barrel. The bad news is that it is HEAVY! I prefer the old NON-FULL LUGGED BARREL. I have a stainless, fixed sight early model and it shoots well enough with the old Ruger rubber grips that I have left it as is. I may have it Magna-Ported, when I get a chance.
I also have several Security Six and a Speed Six. I bought the Security Six used at a gun shop after trying the trigger. It was terrific and as good as my favorite SMITH & WESSON'S. It is one of my favorite revolvers. It is about the same size as a S&W K-frame, so it is lighter than the GP-100 and much more pleasant to carry on my hip.
I bought the Speed Six when I saw it and just had to have it. It looked so good. It had a smooth trigger and shot well with .38 Special and +P, but when I tried .357 magnum ammo, I had to stop. Those small wooden (banana style) grips were just not up to the job. I put a pair of PACHMAYR round butt grips and it was a night and day change. I would love to find a stainless Speed 6 with a round butt and 4 inch barrel. It might be the best ccw revolver ever.
