The "Big shot Grip" might help you make it. It was once made by Fajhen ( I don't think my spelling is right ) and now made again by GBO sponsor Gunstocks, Inc. That grip has a pistol grip with a large loop behind it for the left hand to grip. It was fairly common a number of years ago. Your hands got into a little push/pull contest and it actually made for a pretty steady hold. The loop might add as much as 6" to the length of the grip. The bad news is...I think it is just made for the old Contender and not the G-2. Good Luck` Walt
BTW...When I was stationed in Germany, Bill Ruger had just introduced the Super Blackhawk. I immediately got one thru the post Rod & Gun Club. The Germans wouldn't let me hunt with that either but they sure did get a hoot out o' shootin' it at their local range....whoa..talk about old memories...Thanks.
