Interesting, Chubby, that both a Glock and a 1911 worked for you. I'm not surprised to hear that the 345 works as well, since manufacturers are evidently putting a lot more thought into this aspect of their engineering nowadays, but you're certainly fortunate to be able to shoot such diverse designs naturally. Must be hard when folks start a "1911 vs. Glock" argument with you in the room!
The Rohrbaugh R9s actually points better for me than any other gun I've tried. I complimented Karl Rohrbaugh on this and he told me that, when he was designing the gun, he put a laser pointer atop the wooden model of the frame he was carving and messed with it until it pointed perfectly for him. Then he made the aluminum frame duplicate the feel of the wooden model.
Sort of neat to hear how he did that.
Surprisingly, J-frames point pretty well for me, if I index my thumb on the top of the stocks. Not perfect, but good enough for government work . . .
I imagine that when Gaston Glock developed the Glock among the world's leading LE authorities he also had a team of biomechanical engineers and orthopedic consultants that perfected the "just right" grip angle.
However, in spite of my above "flight of fancy", he probably did start something since all of Springfields XD ads seem to hang onto the bio mechanical part and the new S&W autos all have interchangable grip backstraps, i.e. M-99 and new M&P semi.
The Glock grip angle (13 deg.) works for me too. For what it is worth, I remember reading somewhere that the grip (angle) was designed for optimum recoil management. Unfortunately, I don't remember where I read this info. If I can find it, I will post the source.
