Cooper on Grip Safeties

"We notice that the extrusion at the bottom of the grip safety on the 1911 (the "tang tumor"?) is practically standard with today's custom pistolsmiths. It may work for some people, but it never has worked for me. Apparently my hand is not constructed correctly, so I simply pin the device shut. It is not a safety consideration, as John Browning made clear in his design of the excellent P35 pistol. Safety does not ride between the hands, but rather between the ears."
