So all Blackhawks old or new have the same size grip frame ?
Nope. '55-'62 have the XR-3, a copy of Colt's SAA grip.
'62-Current have the XR3-RED, EXCEPT for the 50th Anniversary .357 and .44 which have a steel, in lieu of cast aluminum, version of the '55-'62 design, but, with the "LOCK".
Now, toss the .41 Mag and .44 Special Flattops in the pot. Both, I believe, have the '05 introduced XR-3, but, I'm not positive. Never seen one here in the desolation of Wyoming..
www.gunblast.com has a good article posted on Ruger Grips and Grip Frames.
