NRA Museums senior curator Doug Wicklund brings two firearms to show John Popp in the Curator's Corner. They have a lot in common, yet are a century apart. This Colt Police Positive Special chambered in .32-20 dates to 1915. It features a "night sight for firearms," as patented by George Seely of San Francisco. A small flashlight is attached beneath the barrel. The wires travel through a highly-modified frame, terminating in squeeze panels in the grip to turn the light on and off. Because the bulb was fragile, it was spring and rubber buffered to absorb recoil. It was a neat idea, but the lighting was weak and it used a lot of batteries. "Flash" forward to 2015, and you have the Glock 19 4th Generation 9mm. A laser has replaced the flashlight, but they both use three-volt batteries and have four adjustment screws.
