I'm not new to the world of firearms but I am to Ruger revolvers. The two I've got my eye on are the KGPF-330 and it's twin brother with the blue finish the GPF-331. Anyone have any experience with either of those models? I'm looking at one as a possible carry piece. I really like the look of them. There not as big as most S&W's yet not too small like most snubbies. My second question would be are these revolvers just a part of the GP-100 series? That's probably a dumb question but Ruger's website doesn't explain it too well. Thanks for your help.
