Blue and pink Justifiers were made for the Super Nintendo Entertainment System and a redesigned green one was made for the PlayStation.
The Konami Justifier is a light gun released by Konami and used in numerous home console games. Konami released variations of the gun for the Sega Mega Drive/Genesis, Sega CD, Super Nintendo, and PlayStation consoles. The original gun was similar in appearance to a Colt Python. During the early 1990s, it was controversial in that it was realistic and used in equally realistic, violent video games. It was used as an example in the United States of America (US) congressional hearings of 1992 to 1993. The guns were originally designed for use with the home versions of Konami's Lethal Enforcers games, although they are compatible with some other games as well.
The original versions for Sega and Nintendo's consoles were modeled after the replica revolvers used in the original arcade version of Lethal Enforcers. The blue Justifier gun connects directly to the console. Optionally, a pink Justifier can be daisy chained into the blue gun rather for use by a second player. The PlayStation version of the lightgun (Sony ID: SLEH-00005, SLUH-00017) is green in color and only works in the first controller slot on the original design of the PlayStation 2. The green Justifier was also the first light gun for the PlayStation, the second being Namco's GunCon.
