Great research Ron, and a great post... This kind of information exchange is what makes this forum great.

I think the differences in grip angles is small enough that it can be attributed to distortion introduced during the camera capture of the images and during publishing...

I would like to add my $0.02 about the differences in the size of the exposed grip safety... I think it may be that the grip safety spring may not have exposed the pressure piece completely in one of the photos and that they are in fact the same size... just showing less in one photo... I make this assumption on the physical location of the safety bar (at the sear) which also appears to be not completely engaged in the same photo.

Comments on this aspect are certainly invited.

My thanks to you all for a lively and informative discussion.
