this past weekend i attended a gun show and found two different tables selling a type of gp100 i hadn't seen before. half-lug, blued, smooth wood grips, 357 magnum, with a 6 round cylinder. for the life of me i cant find anything about this variation. i see on the ruger sight that there is a Lipsy's distributor exclusive that is almost exactly what i found, except they are only listed as 327 and 44 special. does anybody have information on the model i found? is this a new model?
