Which of the following is an example of an offensive weapon that is prohibited?

A sawed-off shotgun is classified as an offensive weapon under Pennsylvania law due to its design, which significantly reduces its length and therefore its intended use in law enforcement or hunting contexts. These firearms are typically viewed as more dangerous because they are easier to conceal and can be used for various aggressive purposes.

The law specifically identifies offensive weapons as those that are designed for offensive use and not for lawful purposes such as self-defense or recreation. In this case, the sawed-off shotgun fits the criteria of an offensive weapon due to its modified structure that enhances its lethality and potential for harm in confrontational situations.

In contrast, while other items listed may have tactical or defensive capabilities, they do not inherently possess the same classification as offensive weapons. For instance, a revolver, although a firearm, is more commonly recognized for lawful personal defense. Handcuffs are tools used by law enforcement for restraint rather than as weapons, and a taser, while capable of incapacitating someone, is generally classified as a non-lethal weapon that is used in specific situations, often in law enforcement contexts, making it less likely to be viewed as an offensive weapon under this particular law.
