I have an 86-prefix New Model Super Blackhawk .44Mag., and a 48-prefix New Model Blackhawk 45LC., both of which I put Hogue Monogrips on as they fit me better than the 'plowhandle' Ruger grips.
I just picked up 521-prefix (2014) New Model Blackhawk 45LC/ACP convertible, and found that the Hogue grip doesn't fit.
As stated by Hondo44 above, it has the XR3 7/16" steel grip frame which is contoured slightly differently, and the grip locator roll-pin is positioned differently than the XR3-Red frames.
Am I correct in assuming (hoping) that a Pachmayr RB03137 Presentation grip will work on it, or can be modified to work ??
Thanks in advance, DaveF.
