Can't believe we haven't had any votes for the GP-100. Does anyone have both that they can photograph together?
The GP-100 has a beefier cylinder, which adds not only to the weight but to the buldge. Also, how tough is it to get a tapered barrel on a GP-100?
If you take the grips off of both guns, you'll also see that Ruger cut some costs on the frame of the GP-100. The Security-Six still looks good without grips, but the GP-100 looks a little incomplete. A photo of that comparison would be neat, too.
