DAYTON, Ohio -- A pistol the size of your smart phone could be on the market soon."You press the safety and the handle will deploy."It looks like something from James Bond, transforming from the size of your phone to a deadly weapon. But Kirk Kjellberg - the creator of the "cell phone gun" - told WKEF it's perfectly safe and for the public."I just decided there's probably gotta be a better way to carry and I was just looking around and noticed everyone had a smart phone so why not make a pistol that would look like that?" Kjellberg said.Kjellberg said they spent a year engineering it and got approval from Bureau of Alcohol Tobacco and Firearms."As long as the pistol has rifle barrel and cannot be fired in closed position it is a pistol," he said."I can't speak for all others but I wouldn't touch it with a ten-foot pole," said Jeff Pedro, a CCW instructor and former police officer. "Overall my professional opinion is it's just a bad idea from a safety perspective and also from an access perspective the inability to get it out, get it functional in a rapid situation would be extremely difficult."Then there's the way it looks. Could it catch police off-guard? Pedro says not likely because it has to be released from its disguise before firing.Jeff Pedro, Former Police Officer: "If the gun were to be released police officers would be alerted to it and they'd pretty much be checking any cell phone that resembled the size and shape of that particular device," Pedro said.Kjellberg said they have the transformation down to seconds but says they've also consulted with cops."It's easier to shoot someone in a nefarious way to shoot someone with a regular pistol than it would be with ours," Kjellberg said.Kjellberg said the guns will be mass produced and should be available for purchase by the end of this summer.
