Belt Buckle Derringer
Toy guns can be harmful for a variety of reasons, but the most common one is when a cop mistook them for the real thing. One of the reasons toy manufactures began producing Belt Buckle Derringer out of various colored plastics or adding bright orange pieces to the ends of their muzzles was because of this. Toy firearms used to appear just like real guns, and the Belt Buckle Derringer by Mattel was one of them. This gun was fashioned into a belt buckle and was the same size as a real derringer. It fired a metal shell that was loaded with a spring-loaded plastic bullet. The bullet would be about the same size and form as a.22-caliber rifle slug and would be fired about 12–15 feet from the gun.
Because it appears and performs like a gun, it isn't always a deadly toy. It's dangerous since it's a trash gun that can lodge a small bullet into someone's eye or down their throat. This plastic, crotch-shot round of fun was most often the unfortunate receiver of the eye, which made it particularly deadly. In addition, you had to put an explosive cap in the gun to generate the appropriate "bang" sound. It's up to you how close you want to put an explosive to your trash, but this was a deal-breaker for a lot of folks.
