Hey Walt you keep making this claim, how about you get a piece of Carcano sized pipe, cover it in ink, grab it then take a photo of your hand and show us how little or how much contact you make, K?

Sounds like a good way for you to LEARN....that an adult male could not wrap his palm around a rifle barrel that is the diameter of a AA pen Light battery, and deposit an identifiable print..... However, You have reversed the situation....the idea would to be ink the palm and grab a AA pen light battery or any cylinder that is close to 16 mm in diameter.....and see how much of a identifiable print you would deposit on that cylinder.....
Since I own many Carcanos I can affirm the fact that an identifiable palm print could not be deposited on the barrel...
If you've got the guts...post a good copy of CE 639 that shows the so called "palm Print" then we'll discuss the idea with the print right there ......
