I don`t have a G-2, but I do have acouple of Encores and acoupe of older Contender. I shoot both and like both. My favorite summer time carry gun is a .17 AH on a Contender frame. I just bought a new .204 Ruger for an Encore frame, went with the Encore barrel because it`s longer. What it boils down to is, the contender is alittle liter, but the Encore will handle bigger cals. and is alittle easier to hold off hand do to the extra weight. If you want bigger cal. you need an Encore. If not eather will work fine.
