All - sorry for the poor pics, but after reading what folks wrote here, I ordered a pair of the old style grips from Ruger Online...and they arrived 24 hours after I ordered!
They feel GREAT on MY hand - filling, but smooth on the sides and easy for me to get all three lower fingers on to the grip where I want them.
Also, see the original Alaskan Hogue with the old style
In this picture, I put the Hogue back over the Ruger old style (ROS?). They bury the ROS, and lower where my bottom 3 fingers need to go.
Finally, I fired the Alaskan for the first time yesterday afternoon...all 7 rounds of 44 ammo that I still had. Just got 300 rounds delivered, so I'll do some more shooting this weekend. However, with the Hogue, what hurt wasn't so much the backstrap area, but the sides of my palm. The sticky rubber acted like checkering and scrapped against my skin with the gun movement. I think the new ROS will perform better, and let the gun slip a bit - but since my bottom 3 fingers will be wrapped comfortably around the grip, I should be able to bring it back into place by just squeezing, the way I do with my Dan Wesson using small grips.
